## Overview (as of 2026-10-29, from 23 sources)

Proposition 39 would require government-issued ID to vote in person and, for mail ballots, the last four digits of an ID number matching one the voter designates in their registration; officials could count a ballot only after verifying identity  [Text of Proposed Law: Proposition 39 (Official Voter Information Guide, Text of Proposed Laws, PDF pages 34–35); Proposition 39 analysis (November 3, 2026 ballot)]. It also orders 'best efforts' citizenship verification of voter rolls with annual county reporting, a free state voter ID card, odd-year State Auditor audits, and citizen lawsuits to enforce compliance  [Text of Proposed Law: Proposition 39 (Official Voter Information Guide, Text of Proposed Laws, PDF pages 34–35); Proposition 39 analysis (November 3, 2026 ballot)]. The text defines qualifying ID only as documentation allowing 'conclusive verification' of identity, leaving ID types, citizenship-check methods and error handling to the Legislature  [Proposition 39 analysis (November 3, 2026 ballot); California Budget & Policy Center on Proposition 39]. The LAO estimates state and local costs of tens of millions to low hundreds of millions of dollars a year  [Proposition 39 analysis (November 3, 2026 ballot)]. Because about 13 million of 16 million 2024 ballots were cast by mail, the mail-ballot rule is the measure's largest practical effect  [CA Decides: Proposition 39; Proposition 39 analysis (November 3, 2026 ballot)]. Two court rulings in August 2026 shaped the campaign: a judge upheld the Attorney General's ballot title, which proponents called biased, and another found proponents' claims that the measure makes voting easier, protects privacy and saves money false or misleading; proponents revised them  [Sacramento Superior Court ruling denying petition over Prop 39 ballot materials; Democrats win court fights over Calif. Voter ID measure]. As of October 22, 2026, the Yes committee had reported about $36.6 million and opposition committees about $33.6 million  [Proposition 39 ballot measure contribution totals]. A September PPIC poll found 43% support  [California voter ID Proposition 39 campaign].

### Record highlights
- August 6, 2026: Judge Jennifer Rockwell upheld the title 'Prohibits Citizens From Voting Unless They Present Government-Issued Identification,' reasoning that a ballot that will not be counted does not accomplish a vote [S7, S8]. [Sacramento Superior Court ruling denying petition over Prop 39 ballot materials; Democrats win court fights over Calif. Voter ID measure]
- August 2026: Judge Shelleyanne Chang found proponents' statements that Prop 39 makes voting easier, improves privacy and saves money false or misleading, in a suit by Speaker Robert Rivas and Senate President pro Tem Monique Limón; proponents removed or revised them [S6, S8, S9]. [Rivas and Limon lawsuit over Proposition 39 voter guide language; Democrats win court fights over Calif. Voter ID measure; Voter ID supporters drop claims ballot measure would save money, make voting 'easier']
- Campaign money through October 22, 2026: Yes $36,561,050 (one committee); No $33,576,498 across ten committees, led by a labor-backed committee at $19.8 million [S3]. Richard Uihlein gave $17 million and Joe Gebbia $8 million to Yes; the California Democratic Party gave nearly $5.5 million to No [S20]. [Proposition 39 ballot measure contribution totals; California voter ID Proposition 39 campaign]

### Stated positions
- Assemblymember Carl DeMaio, the leading proponent, calls it 'a bipartisan, common-sense reform to restore public trust and confidence in our elections' (September 2026) [S17, S22]. [Prop 39 opponents rally against California's proposed voter ID law; Republicans campaign in Fresno for California voter ID measure]
- Sen. Alex Padilla, an opponent, ties it to 'Donald Trump and the MAGA agenda' (September 2026) [S17]. [Prop 39 opponents rally against California's proposed voter ID law]

### Where sources disagree
- Some reports describe the measure as requiring 'proof of citizenship to vote' [S17]; the text and official summaries describe citizenship verification of voter rolls by officials, not proof from voters at the ballot [S2, S5]. [Text of Proposed Law: Proposition 39 (Official Voter Information Guide, Text of Proposed Laws, PDF pages 34–35); Proposition 39 analysis (November 3, 2026 ballot); Prop 39 opponents rally against California's proposed voter ID law]
- Effect on turnout: proponents say states with voter ID and free IDs saw participation rise [S18]; opponents cite Texas rejecting 12 times more mail ballots than California [S18], and the Budget Center cites studies finding little effect on confidence [S16]. [California Budget & Policy Center on Proposition 39; Proposition 39 arguments and rebuttals]
- Whether existing voters must effectively re-register to designate an ID: the Budget Center and the League say yes [S12, S16]; the LAO says only that voters must select an ID in their registration [S5]. [Proposition 39 analysis (November 3, 2026 ballot); No on Prop 39 Fact Sheet; California Budget & Policy Center on Proposition 39]
- Yes-side fundraising was reported as more than $28 million and then more than $36 million in early October [S20, S21]; the official total through October 22 is $36.6 million [S3]. [Proposition 39 ballot measure contribution totals; California voter ID Proposition 39 campaign; Why are out-of-state billionaires funding a California voter ID measure?]

### Gaps
- No estimate of how many voters lack a qualifying ID under rules the Legislature has not yet written, or how many mail ballots might be rejected.
- No independent study of fraud rates specific to California mail voting.
- Proponent views come mainly from campaign materials and one commentator; the Yes campaign declined interviews [S20].

### Arguments for / praise
- ID requirements increase trust in elections and bring California in line with the 36 other states that request or require ID; the ID card is free, so it is not a poll tax. — *Californians for Voter ID, Bill Jones (former Secretary of State)* [Commentary: voter identification and Proposition 39; Proposition 39 arguments and rebuttals; California voter ID Proposition 39 campaign]
- California does not meaningfully verify citizenship or scrub its rolls of duplicate and deceased registrants, and allows ballot harvesting; Jones says this does not mean fraud is rampant. — *Bill Jones* [Commentary: voter identification and Proposition 39]
- The signature-check system is slow and error-prone; more than 100,000 ballots were rejected for signature mismatches in the last election. — *Californians for Voter ID* [Proposition 39 arguments and rebuttals]
- Mail voting, not in-person impersonation, is the real verification gap, and existing cure procedures could limit rejected ballots. — *Hoover Institution* [CA Decides: Proposition 39]
- Voter ID has bipartisan support: nearly half of qualifying signatures came from Democrats and independents. — *Californians for Voter ID, Carl DeMaio* [Prop 39 opponents rally against California's proposed voter ID law; Proposition 39 arguments and rebuttals]

### Arguments against / criticism
- A single wrong digit, an outdated ID or a name change could void a valid mail ballot, and the text does not require officials to notify voters of errors. — *League of Women Voters of California, ACLU California Action, Common Cause* [No on Prop 39 Fact Sheet; Proposition 39 arguments and rebuttals]
- Putting partial ID numbers on envelopes stored for months raises identity-theft risk. — *League of Women Voters of California, California Budget & Policy Center* [No on Prop 39 Fact Sheet; California Budget & Policy Center on Proposition 39]
- Fraud and noncitizen voting are extremely rare, while about 2.7 million voting-age citizens lack a driver's license; seniors, students, low-income voters and voters of color would be hit hardest. — *California Budget & Policy Center, League of Women Voters of California* [No on Prop 39 Fact Sheet; California Budget & Policy Center on Proposition 39; California voter ID Proposition 39 campaign]
- Citizenship checks against error-prone federal databases would wrongly flag some citizens, and the citizen-suit clause could be used to press officials to act on flawed data. — *California Budget & Policy Center* [California Budget & Policy Center on Proposition 39]
- It costs up to hundreds of millions a year with no funding source. — *ACLU California Action, California Budget & Policy Center* [California Budget & Policy Center on Proposition 39; Proposition 39 arguments and rebuttals]

## Text analysis (as of 2026-10-28)

Coverage: Full text of the proposed law for Proposition 39 from the Secretary of State's Text of Proposed Laws (S2, guide pages 133-134): Sec. 1 (Findings and Purposes), Sec. 2/2.1 (adds Article II, Section 3.1, subdivisions (a)-(c)) and Sec. 3 (Severability). The text is complete. S3 repeats Sec. 2.1 and Sec. 3. S1 is the voter-guide section (title and summary, LAO analysis, arguments) and contains no legal text. S4 (the Attorney General's filed copy) yielded only a header line.

Drafting quality: **mixed**. The measure is short, and its core mandates are stated plainly: ID at the polls, a matching last-four-digit number on mail envelopes, identity and single-ballot verification before any ballot is counted, a free voter ID card, annual citizenship-verification reporting, odd-year State Auditor audits, and a citizen right to seek judicial review. Its severability clause is standard. But the operative terms that decide who can vote are not defined: what counts as 'government-issued identification' ('conclusive verification'), what 'best efforts' and 'government data' mean, and what a 'unique identifying number' is. The text also says nothing about how existing registrants designate an ID, what happens when digits are missing or wrong (notice or cure), or how military and overseas voters relate to the ID rule. It declares itself self-executing and also leaves these choices to legislation that it requires 'promptly' but sets no deadline for, so how the measure applies before that legislation passes is unclear. The LAO's analysis (S1) likewise says the Legislature would need to clarify which IDs qualify and what counts as best efforts. Clear core mandates paired with significant definitional and transitional gaps make the drafting mixed.

- **expansive language** (high, Art. II, Sec. 3.1(b) (added by Sec. 2.1)): This is the only definition of the ID that every in-person voter must present. It lists no acceptable documents, and 'conclusive verification' is a high, undefined standard that could be read narrowly (for example, photo ID only) or broadly. Which voters can vote in person depends on how the Legislature or officials fill this in. — "Government-issued identification means documentation that allows conclusive verification of the voter’s identity." [Proposition 39 Text of Proposed Laws]
- **gap** (high, Art. II, Sec. 3.1(b)): The text makes verification a condition of counting any ballot, including provisional ballots, but provides no notice or cure process for a missing or mismatched ID number, and no deadline for a voter to produce ID after casting a provisional ballot. Whether existing statutory cure procedures carry over is not stated. That choice could decide how many otherwise valid ballots go uncounted. — "Election officials shall only count a regular or provisional ballot after verifying the identity of the person voting pursuant to the requirements of this section" [Proposition 39 Text of Proposed Laws]
- **gap** (high, Art. II, Sec. 3.1(b)): Mail voting depends on a designated ID, but the text sets no transition for voters already registered without a designation, no effective date or phase-in, and no rule for a mail ballot from a voter who has not designated an ID. It is left open how and when existing registrants would designate one. — "The type of identification designated by each voter must be indicated in their voter registration record" [Proposition 39 Text of Proposed Laws]
- **ambiguity** (medium, Art. II, Sec. 3.1(b)): 'Unique identifying number' is undefined. It is unclear whether numbers not printed on a physical ID document, such as a Social Security number or a registration identifier assigned by the state, qualify as being 'from government-issued identification', and only the last four digits are matched, which are not unique on their own. — "the last four digits of a unique identifying number from government-issued identification" [Proposition 39 Text of Proposed Laws]
- **ambiguity** (medium, Art. II, Sec. 3.1(a)): Neither 'best efforts' nor 'government data' is defined, and the text does not say what happens to a registrant whose citizenship cannot be verified (whether there is notice, removal, or no consequence beyond the annual percentage report). Combined with the citizen-suit provision in (c), the undefined standard could be contested in court. — "shall use best efforts to verify citizenship attestations using government data" [Proposition 39 Text of Proposed Laws]
- **ambiguity** (medium, Art. II, Sec. 3.1(c)): The section takes effect without legislation but leaves its key terms to implementing laws, which must be enacted 'promptly' with no deadline. How the ID and verification rules apply to elections held before those laws exist, and what standard officials would use in the meantime, is unclear. Self-executing language is common in California constitutional measures; the uncertainty here comes from pairing it with undefined operative terms. — "This section shall be self-executing. The Legislature shall also promptly enact laws to implement this section" [Proposition 39 Text of Proposed Laws]
- **carve out** (medium, Art. II, Sec. 3.1(c)): This is the only group the text names for separate treatment, and it does not say whether military and overseas voters are exempt from subdivision (b)'s ID and digit-matching rules or must meet them in modified form. The scope of any exception is left to the Legislature. — "provide for voting by military and overseas voters consistent with federal law" [Proposition 39 Text of Proposed Laws]
- **enforcement** (medium, Art. II, Sec. 3.1(c)): This creates a broad constitutional right of action for any citizen against the State or any county. The text does not define the available remedies, standing limits or the standard of compliance, which combined with undefined terms such as 'best efforts' leaves wide room for litigation over administration. — "Citizens may seek judicial review and remedy of the State’s or any county’s compliance with this section." [Proposition 39 Text of Proposed Laws]
- **gap** (medium, Art. II, Sec. 3.1(b)): The text does not name the issuing agency, the documents an applicant must show to get the card, how eligibility is established, or a funding source. Only the card is free; the text does not address the cost of any documents needed to obtain it. Whether the card itself meets the 'conclusive verification' standard depends on how it is designed. — "Upon request by an eligible voter, the State shall provide, at no charge, a voter ID card for use in casting a ballot." [Proposition 39 Text of Proposed Laws]
- **gap** (low, Art. II, Sec. 3.1(b)): Single-ballot verification is made a precondition to counting every regular and provisional ballot, but the text sets no method or timing for it. The text also contains no privacy or data-security provision for the partial ID numbers that mail voters would write on envelopes. — "verifying that the person has cast only one ballot in the election" [Proposition 39 Text of Proposed Laws]
- **duration** (low, Sec. 2.1): Because the rules are placed in the Constitution with no sunset, the Legislature cannot repeal or narrow them by statute; changes would require another constitutional amendment approved by voters. This is inherent to constitutional amendments, not an unusual lock. — "Section 3.1 is added to Article II of the" [Proposition 39 Text of Proposed Laws]
- Beneficiary: Eligible voters who lack another acceptable ID: The State must provide them a voter ID card at no charge on request. — "Upon request by an eligible voter, the State shall provide, at no charge, a voter ID card" [Proposition 39 Text of Proposed Laws]
- Beneficiary: Any citizen, including individuals and organizations acting through citizens, who wants to challenge election administration: The text gives citizens a constitutional right to seek judicial review and remedy of the State's or any county's compliance. — "Citizens may seek judicial review and remedy of the State’s or any county’s compliance with this section." [Proposition 39 Text of Proposed Laws]

Limitations: This analysis reads only the measure's text and does not assess the policy's merits, how existing statutes would interact with it, or how courts would construe it. Many effects depend on implementing legislation not yet written. S4, the Attorney General's copy, yielded no readable text, so no version comparison was made; S2 and S3 agree on the operative section.

### Why are out-of-state billionaires funding a California voter ID measure?

- <https://www.kpbs.org/news/politics/2026/10/07/why-are-out-of-state-billionaires-funding-a-california-voter-id-measure>

A CalMatters news article by Nadia Lathan, republished by KPBS, on who is funding the Proposition 39 campaigns. It details the major Yes-side donors, led by Illinois billionaire Richard Uihlein's $17 million, and the major No-side donors, led by the California Democratic Party, and summarizes each side's arguments, expert commentary on fraud claims and strategy, campaign advertising, and polling.
  - Richard Uihlein had contributed $17 million to the Yes campaign; other Yes donors include Steven Bray (more than $3 million loaned plus $50,000), Reform California, Cameron and Tyler Winklevoss ($250,000 each) and Nicole Shanahan ($370,000).
  - The Yes campaign had raised more than $28 million, $11 million more than opponents, about a month before Election Day.
  - No-side donors: California Democratic Party (nearly $5.5 million), Federated Indians of Graton Rancheria ($2 million), Patty Quillin and Quinn Delaney ($1.5 million each), SEIU ($1 million).
  - Assemblymember Carl DeMaio created Reform California and is spearheading the initiative after similar bills failed in the Legislature.
  - Opponents including Common Cause and the League of Women Voters argue it would block citizens without ID and that fraud is rare; supporters compare ID to needing ID to fly or buy alcohol.
  - Nearly 90 percent of Californians vote by mail per the Secretary of State, so most voters would write ID digits on envelopes.
  - An April UC Berkeley IGS poll found broad support for ID that fell below 50 percent with specifics; a September PPIC poll found 43 percent support for Prop 39.

### Proposition 39: Require identification for voting
- CalMatters · voter guide · published 2026-10-01 · stance: neutral
- <https://calmatters.org/california-voter-guide-2026/proposition-39-voter-id/>

CalMatters' 2026 voter-guide entry for Proposition 39. It briefly explains the measure, summarizes each side's main argument, lists endorsements on each side, links paired commentaries and related news, explains its campaign-finance data methods, and reprints the official ballot text.
  - CalMatters describes the measure as requiring ID at the polls, ordering officials to verify that all registered voters are citizens, and requiring the last four digits of a government ID on mail ballots.
  - It says California currently requires ID and Social Security information to register but does not request ID at polling places.
  - It says the measure was placed on the ballot by conservative groups.

### Proposition 39 arguments and rebuttals
- California Secretary of State · position statement · published 2026-09-28 · stance: mixed
- <https://vig.cdn.sos.ca.gov/2026/general/pdf/prop39-arg-rebuttals.pdf>

The official ballot arguments for and against Proposition 39, with rebuttals, as printed on pages 52-53 of the state Voter Information Guide. The argument in favor and the rebuttal to the argument against are signed by leaders of Californians for Voter ID and allied groups; the argument against and the rebuttal to the argument in favor are signed by ACLU California Action, Common Cause, the League of Women Voters of California, U.S. Sen. Alex Padilla, the California Nurses Association and the California School Employees Association. The guide notes the arguments are the authors' opinions and were not checked for accuracy by any official agency.
  - Supporters argue voter ID is a bipartisan, common-sense reform that increases trust and participation, and that the measure keeps mail ballots and other conveniences while guaranteeing a free voter ID.
  - Supporters argue the current signature-check process is slow and that more than 100,000 ballots were rejected for signature mismatches in the last election.
  - Supporters say the measure requires citizenship checks of voter rolls and an independent audit every two years.
  - Opponents frame the measure as tied to Donald Trump and 'MAGA' billionaire funding and call it election rigging.
  - Opponents argue it would cost hundreds of millions of dollars, citing the LAO, and that putting ID digits on mail envelopes creates identity-theft risk.
  - Opponents argue a single wrong digit, an out-of-date ID address or a misspelled name could cause a valid ballot to be rejected, and that voters who do not designate an ID may not get a mail ballot.
  - Opponents argue 'free' IDs still impose costs such as travel, time off work and obtaining documents, hitting seniors, students, low-income workers, voters of color and women who changed names hardest.

### Prop 39 opponents rally against California's proposed voter ID law

- <https://kioncentralcoast.com/news/top-stories/2026/09/09/prop-39-opponents-rally-against-californias-proposed-voter-id-law/>

A KPIX report syndicated by KION 46 on a Proposition 39 opposition rally. It explains current California ID rules and the measure's requirements, quotes the LAO cost estimate, and gives quotes from Sen. Alex Padilla (opposed), Assemblymember Carl DeMaio (supporter), and CSU Long Beach professor Matt Lesenyie. It also cites an April UC Berkeley IGS poll.
  - Current law requires ID and a Social Security number to register; IDs are not required at the polls and mail ballots are verified by signature.
  - The report says that if passed, Prop 39 would require proof of citizenship to vote, ID at polling stations, and the last four ID digits on mail ballots.
  - Quotes the LAO: costs could increase by tens of millions to low hundreds of millions of dollars a year, less than 0.25 percent of the General Fund, with savings likely not exceeding costs.
  - At the rally, Democrats called the proposal a Republican-led assault to disenfranchise voters; Sen. Padilla tied it to 'Donald Trump and the MAGA agenda.'
  - DeMaio called it a bipartisan, common-sense reform and 'the most important ballot measure' in decades, and said 1.4 million signatures were collected, nearly half from Democrats and Independents.
  - Election officials said audits show the mail system is secure with no evidence of widespread fraud; Prof. Lesenyie called the measure 'a solution in search of a problem.'
  - An April UC Berkeley IGS poll found 56 percent of voters supported the measure.

### California Budget & Policy Center on Proposition 39
- California Budget & Policy Center · third party analysis · published 2026-09 · stance: oppose
- <https://calbudgetcenter.org/?p=49949>

A California Budget & Policy Center issue brief (September 2026, by Scott Graves, Alissa Anderson and Leslie A. Ortiz) that explains Proposition 39's provisions against current law and argues against the measure. It contends the measure addresses a nonexistent fraud problem, would create barriers for millions of eligible voters, increase identity-theft risk, lead to citizens being wrongly flagged as noncitizens, and impose unfunded state and local costs, and it places the measure within a national push to restrict voting.
  - Explains each provision against current law: 'best efforts' citizenship verification with 'government data' (both undefined), ID at polls, designation of an ID for mail voting (which the Center says effectively requires existing voters to re-register), last four digits on the envelope, a free voter ID card, odd-year State Auditor audits, required implementing laws, and citizen lawsuits.
  - Notes the measure defines government-issued ID only as 'documentation that allows conclusive verification of the voter's identity,' leaving acceptable ID types to the Legislature.
  - Notes the citizen-suit provision does not specify what evidence is needed to sue.
  - Cites Brookings, Brennan Center, Bipartisan Policy Center and Cato research that voter fraud and noncitizen voting are extremely rare.
  - Cites a VoteRiders/CDCE survey: about 2.7 million (10.8%) voting-age citizen Californians lack a driver's license and more than 3 million (12.6%) have one that is expired, out of state or out of date.
  - Argues ID digits on envelopes, which must be stored 6 to 22 months, raise identity-theft risk, citing NIST guidance on partial identifiers.
  - Argues error-prone federal databases would cause some citizens to be wrongly flagged, and that the private right of action could be used to press officials to act on flawed data.
  - Cites the LAO cost estimate and argues costs would come without new revenue, alongside federal H.R. 1 cuts.

The Secretary of State's 'Text of Proposed Laws' pages (pages 133-134 of the Voter Information Guide) containing the complete legal text of Proposition 39, preceded by the end of Proposition 38's text and followed by the start of Proposition 40's. Prop 39 has three sections: findings and purposes; Sec. 2.1, which adds Section 3.1 to Article II of the California Constitution; and a severability clause.
  - Sec. 1 states the purposes: enforcing existing voter qualifications including U.S. citizenship, promoting public confidence, deterring and detecting fraud by maintaining accurate rolls, and minimizing impersonation by requiring proof of identity.
  - New Art. II, Sec. 3.1(a): the Secretary of State and county officials must maintain accurate registration lists, use 'best efforts' to verify citizenship attestations using government data, and annually report the percentage of each county's rolls that is citizenship-verified.
  - Sec. 3.1(b): in-person voters must present government-issued ID each time; mail voters must provide the last four digits of a unique number from government-issued ID that matches the one they designated for their registration.
  - Sec. 3.1(b): the designated ID type must be in the registration record, noted on the mail-ballot envelope and available by phone or electronically; officials may count a regular or provisional ballot only after verifying identity and that the person cast only one ballot.
  - Sec. 3.1(b) defines government-issued identification as 'documentation that allows conclusive verification of the voter's identity' and requires the State to provide a free voter ID card on request.
  - Sec. 3.1(c): the section is self-executing; the Legislature must promptly enact implementing laws, provide for military and overseas voters, and ensure compliance; citizens may seek judicial review; the State Auditor must audit compliance every odd-numbered year.
  - Sec. 3 is a standard severability clause.

The Proposition 39 section of the official state Voter Information Guide (pages 48-53). It contains the Attorney General's official title and summary, the Legislative Analyst's fiscal summary and full analysis, pointers to campaign-finance information, and the official arguments and rebuttals for and against. Despite being catalogued as official text, it does not contain the measure's legal text, which the guide says is on page 133.
  - Attorney General's summary: prohibits voting by mail unless the voter designates a government-issued ID number for their registration.
  - Invalidates a mail ballot if the envelope lacks the last four digits of an ID number matching the designated one; the summary's example is a voter who designates a Social Security number but writes a driver's license number, whose ballot would not count.
  - Prohibits voting in person without presenting government-issued identification.
  - Requires elections officials to report annually the percentage of each county's voters whose citizenship status they have verified.
  - LAO estimate: state and local costs of tens of millions to low hundreds of millions of dollars per year, depending on future decisions; possible savings likely would not exceed costs.
  - Includes the same official arguments and rebuttals that are stored as a separate source.

An opposition fact sheet against Proposition 39 published by the League of Women Voters of California and paid for by No on Prop 39 - Californians for Voting Rights (sponsored by California Donor Table and ACLU of Northern California). It describes the measure's requirements and argues it would make voting harder, expose voters to identity theft, cause valid ballots to be rejected, slow counting and waste money, and frames it as backed by 'MAGA Republicans and billionaires.'
  - Argues mail ballots could be rejected unless voters designate a personal ID number and perfectly match its last four digits each election.
  - Says election officials would not be required to notify mail voters who make mistakes or omit the number.
  - Says the measure is unclear on which kinds of ID would be accepted at the polls and which databases would be used for annual citizenship checks.
  - Argues ID numbers on mailed materials create identity-theft risk.
  - Argues seniors, students, low-income voters, people with disabilities, voters of color and people who changed names would be disproportionately blocked.
  - Argues costs would include effectively re-registering over 26 million voters, changing registration systems, more staff, and defending lawsuits.

A Times of San Diego republication of Bill Jones's CalMatters guest commentary supporting Proposition 39. Jones, California secretary of state from 1995 to 2003, argues the measure would make the election system 'harder to doubt' through ID requirements, free ID cards, and accurate voter rolls with citizenship verification, and criticizes the Attorney General's revised ballot title. The text is the same as the CalMatters original.
  - Jones supports Prop 39, arguing that maximum participation and zero tolerance for fraud depend on each other.
  - He describes the measure as requiring ID in person or the last four ID digits by mail, free state ID cards, and accurate voter rolls including citizenship verification.
  - He argues it does not disenfranchise eligible voters or create a poll tax because the ID is free.
  - He says it would bring California in line with 36 other states with some form of voter ID.
  - He criticizes the Attorney General's July ballot-title revision.
  - He says California's voter file has inactive records and the state mails ballots to people who have moved and allows ballot harvesting, while stating fraud is not rampant.

### Sacramento Superior Court ruling denying petition over Prop 39 ballot materials

- <https://www.democracydocket.com/wp-content/uploads/2026/07/2026-08-06-Denial-of-petition.pdf>

The Sacramento County Superior Court's minute order and ruling (Judge Jennifer K. Rockwell, Case 26WM000193, Californians for Voter ID, Yes on 39, et al. v. Weber) denying the proponents' petition for a writ of mandate against the Attorney General's ballot title, summary and label for Proposition 39. The court held that the title 'Prohibits Citizens From Voting Unless They Present Government-Issued Identification' accurately describes the measure and that the Attorney General reasonably left out subdivision (a) duties that reflect existing law.
  - Petitioners argued the title was false or misleading because Prop 39 regulates which ballots are counted rather than whether a citizen may cast one ('a verification rule, not a disqualification').
  - The court rejected this, reasoning that the text requires voters to present ID when casting a ballot in person and to provide the matching ID digits when voting by mail, so it 'imposes substantive restrictions on the submission of ballots.'
  - The court added that voting includes having one's ballot counted, citing Gould v. Grubb (1975), so a ballot that will not be counted does not accomplish a vote.
  - On the petitioners' claim that the title omits subdivision (a)'s duties to maintain accurate rolls and verify citizenship, the court accepted the Attorney General's position that those duties largely reflect existing law and that annual citizenship reporting is the only new requirement.
  - The court held that differences from the circulating title and the LAO's description are irrelevant under Elections Code section 9051, which allows the ballot title to differ.
  - The court found petitioner Donald DiCostanzo had standing; the petition was denied.

  - Judge Shelleyanne Chang sided with Speaker Robert Rivas and Senate President pro Tem Monique Limón, finding all challenged supporter statements (easier voting, improved security and privacy, taxpayer savings) false or misleading; supporters agreed to remove or revise them.
  - Chang reasoned an added ID step cannot reasonably be called making voting easier, and the privacy claim misled because mail voters put part of an ID number on the envelope.
  - Judge Jennifer Rockwell rejected Californians for Voter ID's challenge to the title 'Prohibits Citizens From Voting Unless They Present Government-Issued Identification,' noting provisional ballots still require ID before they count.
  - Cites the LAO estimate of tens of millions to low hundreds of millions of dollars a year in costs.

The verified petition for writ of mandate filed July 29, 2026 in Sacramento Superior Court by Assembly Speaker Robert Rivas and Senate President pro Tempore Monique Limón (represented by Olson Remcho LLP) against the Secretary of State and State Printer, with the authors of the pro-Prop 39 ballot arguments as real parties in interest. It asks the court to strike statements in the Argument in Favor, the Rebuttal to Argument Against and the Ballot Argument Summary claiming that Prop 39 makes voting easier, contains privacy protections, makes sure every valid vote counts by improving on signature verification, and saves money.
  - Petitioners argue it is false that Prop 39 'makes it easier to vote', since current law requires no ID to vote, and false that it 'requires no burdens' or that 'no additional documents' are required.
  - Petitioners argue the measure contains no privacy provisions and instead requires mail voters to disclose part of an ID number through the mail.
  - Petitioners argue nothing in Prop 39 mentions or changes signature verification, so the argument implying it replaces signature checks is misleading.
  - Petitioners argue the measure would prevent otherwise valid ballots from counting when the ID digits do not match the designated number.
  - Petitioners cite the LAO's estimate of costs between tens of millions and low hundreds of millions of dollars a year to dispute the claim that Prop 39 'saves money.'
  - Petitioners describe current law: voters attest citizenship under penalty of perjury at registration; in-person voters sign the roster; mail voters sign the envelope (Elec. Code 2000, 3011, 14216, 14310).
  - Petitioners note that voters who registered before HAVA took effect may not know whether they have a designated ID number.

### Proposition 39 analysis (November 3, 2026 ballot)

- <https://lao.ca.gov/ballot/2026/prop39-110326.pdf>

The Legislative Analyst's Office's impartial analysis of Proposition 39 for the November 3, 2026 ballot. It describes current California law on citizenship, registration, voter-roll maintenance and voter identification (signatures), then explains what the measure would require: citizenship verification of voter rolls using 'best efforts', designation of a government-issued ID for mail voting, ID at in-person voting, the last four digits of that ID on mail envelopes, a free state voter ID card, odd-year State Auditor compliance audits, and further legislation. It estimates annual state and local costs of tens of millions to low hundreds of millions of dollars.
  - Currently, voters identify themselves by signing the roster in person or signing the mail-ballot envelope; officials verify mail-ballot signatures but generally not in-person signatures.
  - Prop 39 requires officials to use 'best efforts' with government data to verify that registered voters are citizens and to report yearly the share of each county's voters verified.
  - Voters would have to select a government-issued ID in their registration to vote by mail and write the last four digits of that ID number on the envelope; in-person voters must present government-issued ID.
  - The state must provide a free voter ID card on request.
  - The State Auditor must report on state and county compliance every odd-numbered year.
  - The Legislature would need to define details the measure leaves open, such as which IDs qualify and what counts as best efforts to verify citizenship.
  - Fiscal estimate: state and local costs of tens of millions to low hundreds of millions of dollars per year, depending on future decisions; possible savings from fewer registered voters likely would not exceed costs.

### CA Decides: Proposition 39
- Hoover Institution · third party analysis · published undated · stance: neutral
- <https://www.hoover.org/proposition-lab-proposition-39>

A Hoover Institution 'California Decides / Proposition Lab' explainer on Proposition 39. It describes the measure's ID requirements for in-person and mail voting, the citizenship-verification and reporting duty, the free state ID card, the self-executing clause, citizen suits and odd-year audits, and the ballot-title dispute. It then discusses trade-offs, focusing on mail voting, ballot harvesting and declining voter confidence. While saying it does not tell voters what to think, its conclusion characterizes the measure as addressing a real gap and argues the Legislature could limit rejected ballots through a cure process.
  - Says the measure's largest effects would fall on mail voting, since over 80 percent of Californians vote by mail.
  - States there is no credible proof of widespread or systematic election fraud in California, but that instances have been uncovered and confidence in elections has declined.
  - Reports that the AG changed the title from 'Establishes Additional Voter Identification and Citizenship Verification Requirements' to the current title, and that the Sacramento Superior Court found the changed title and summary 'sufficient.'
  - Compares the mail-ballot ID-number system to Minnesota's, which also requires a witness.
  - Argues that in-person impersonation is the rarest form of fraud and that mail voting is the larger verification gap.
  - Concludes that passage would bring California in line with most states, that voter ID has broad support, and that existing ballot-cure procedures could address rejected ballots.
