Proposition 4: Repeals Prohibition Against Public Funding of Election Campaigns

LAist's voter guide entry on Prop. 4 by Nick Gerda (updated October 20, 2026) explains the measure, both sides' arguments, notable supporters and opponents, fiscal impact, and a Los Angeles cost comparison.

• LAist says the measure would repeal the ban on the state and most local governments using tax dollars for candidate campaigns, and would triple the maximum fine for foreign contributions.
• LAist reports that public financing is currently allowed for charter counties and cities, and that five charter cities have programs: Los Angeles, Long Beach, Oakland, San Francisco, and Berkeley.
• LAist says the Legislature placed the measure on the ballot on a party-line vote, and that a similar 2016 law was struck down because it required a statewide vote.
• Notable supporters: California Democratic Party, League of Women Voters of California, California Nurses Association, California Clean Money Campaign, California Common Cause.
• Notable opponents: California Taxpayers Association, Howard Jarvis Taxpayers Association, California Hispanic Chambers of Commerce, former FPPC Chair Dan Schnur.

CalMatters' 2026 voter guide entry for Prop. 4 summarizes advocates' and opponents' arguments, lists organizational and newspaper endorsements, and repeats the ballot label.

• Advocates say public financing curbs private money's influence, encourages candidates without big backing, and empowers small donors.
• Opponents say taxpayers would subsidize candidates they may not support, funds could go to fraudulent candidates, and setting up programs is expensive.
• Listed organizations include California Common Cause, California Clean Money Campaign, League of Women Voters, California Democratic Party, California Taxpayers Association, and Reform California.
• Listed media endorsements are the Sacramento Bee, San Diego Union-Tribune, Orange County Register, and San Francisco Chronicle.

The voter guide's pages containing the Attorney General's official title and summary for Proposition 4, the Legislature's final votes on SB 42, and the Legislative Analyst's analysis.

• The Attorney General's summary says current law prohibits state and local governments from using public funds for election campaigns except in charter cities and counties, and that the measure repeals that prohibition.
• It lists the bar on using funds earmarked for education, transportation, or public safety, and the bar on using public funds for legal defense, fines, or repaying personal loans.
• It states that the measure triples the maximum fine for campaign contributions by foreign entities.
• Final legislative votes on SB 42: Senate 29-8, Assembly 59-20.
• The LAO analysis portion matches the LAO's standalone analysis.

The voter guide's printed text of Proposition 4 (SB 42, Chapter 245, Statutes of 2025), the California Fair Elections Act of 2026. It contains legislative findings, a rewrite of Government Code Section 85300 (the 1988 ban on public campaign funding), and amendments to Section 85320 on foreign contributions. The stored extract also contains the end of Proposition 3's text and the start of Propositions 5 and 37, because the PDF pages are shared. Strikeout and italic formatting is lost, so deleted and added wording appear side by side.

• Section 85300(a), as amended, bars a public officer from spending, and a candidate from accepting, public funds for seeking elective office if the funds are earmarked by any state or local entity for education, transportation, or public safety.
• Candidates must abide by expenditure limits and meet 'strict criteria' to qualify, which must require broad-based support in the district (for example small-dollar contributions or vouchers); qualifying contributions counted cannot be required to exceed $10, and signature or total-dollar thresholds are excluded.
• Public funds may not pay legal defense fees or fines or repay a candidate's personal loan; a publicly funded candidate may not repay a personal loan from any source after the campaign ends.
• Programs may not discriminate by party or between challengers and incumbents; a jurisdiction may raise a participating candidate's spending limit using a 'net supportive funds' formula tied to opponents' funds and independent expenditures.
• The Fair Political Practices Commission is not responsible for administering or enforcing local programs.
• Subdivisions (e), (f), and (h) may be amended by statute under Section 81012(a); the remaining subdivisions only by a statute complying with Section 81012(b).
• Section 85320 (printed as SEC. 4.1) restates the ban on foreign contributions and adds a fine of at least the amount contributed and up to three times that amount.

The Legislative Analyst's Office analysis of Proposition 4 explains the Political Reform Act's ban on public funds for campaigns (with exceptions for certain charter cities), what the measure changes, and its fiscal effects.

• The LAO says the ban applies to most state and local offices but not to city elections in certain charter cities; Los Angeles, San Francisco, Long Beach, Oakland, and Berkeley currently provide public funds to certain campaigns.
• The LAO says the measure lifts the ban and sets broad rules but leaves many key design decisions to future state and local decision makers; it does not create a program directly.
• Rules described: no use of money meant for education, transportation, or public safety; candidates must show broad-based support and accept spending limits; no use for legal defense, fines, or repaying personal loans.
• The FPPC is not required to administer or enforce local programs but could give guidance.
• The LAO says program costs could be significant for governments that create them and depend on future decisions; it estimates FPPC costs of a few hundred thousand dollars a year.

The Secretary of State's official voter guide landing page for Proposition 4 gives the ballot summary (repeals the prohibition on state and local public funding of candidate campaigns; programs may not use funds earmarked for education, transportation, or public safety), the fiscal impact statement, the meaning of yes and no votes, short pro and con arguments, and contacts for each campaign.

• Placed on the ballot by the Legislature as a legislative statute.
• Fiscal impact: ongoing state costs of a few hundred thousand dollars a year for the Fair Political Practices Commission to answer questions from state and local governments about public campaign finance programs.
• A yes vote means state and local governments could create public campaign financing programs, subject to limits on which public funds could be used, how they could be used, and who could receive them; a no vote means state and most local governments would remain unable to do so.
• Listed supporters: League of Women Voters of CA, California Nurses Association, Mental Health Advocacy, Social Security Works, Consumer Watchdog.
• Listed opponents: California Taxpayers Assn, Howard Jarvis Taxpayers Assn, Family Business Assn of California, United Latinos Action.

The official ballot arguments for and against Proposition 4 and each side's rebuttal, as printed in the state voter guide. The state notes that the arguments are the authors' opinions and have not been checked for accuracy.

• The argument in favor, signed by the League of Women Voters of California, the California Nurses Association, and Sen. Tom Umberg, says money is distorting elections and that Prop. 4 lets communities adopt public financing with safeguards.
• Supporters say public funding programs operate in fourteen states and 26 localities, and that a program could cost as little as $1 per resident a year.
• The argument against, signed by former FPPC Chair Dan Schnur, former FPPC Commissioner Colleen McAndrews, and the California Hispanic Chambers of Commerce, calls the measure a 'blank check' with no limit on the number of candidates or the amount of money.
• Opponents say 'strict criteria' are left to future statutes and ordinances written by the same politicians, and that candidates could still take special-interest money.
• The rebuttals are signed by CalTax, HJTA, and Dan Schnur (against) and by Consumer Watchdog, California NOW, and California Common Cause (for).

A Spanish-language Brennan Center for Justice analysis arguing that Proposition 4 would be a powerful way to counter the influence of large donations in California politics, with examples from public financing programs elsewhere.

• The Brennan Center says public financing programs exist in at least 14 states and 26 localities, including five California charter cities, and that state law bars others.
• It describes small-donor matching (Los Angeles, Berkeley, Long Beach, San Francisco, New York), flat grants (Arizona, Connecticut, Maine), and vouchers (Oakland, coming soon).
• It stresses that Prop. 4 does not require the state or any locality to adopt a program.
• It cites New York State's 2024 cycle (about twice as many small donors), Washington D.C., Seattle, and Berkeley, where it says out-of-city contributions fell from 33% in 2016 to 10% in 2018.

A CalMatters guest commentary by Mary Gomes, a Sonoma State University psychology professor, supporting Prop. 4. She argues that the 2026 gubernatorial primary showed California needs public campaign financing.

• Gomes writes that Democratic primary voters faced a choice between a self-funded billionaire, Tom Steyer, and Xavier Becerra, whom she says was backed by large corporate donors.
• She says the measure does not mandate public funding or create a system; it lets state and local governments decide and sets general guidelines.
• She cites research by Paul Piff on wealth and ethics, and by Gilens and Page on elite influence over policy.
• She points to New York City's matching funds program and Zohran Mamdani's mayoral win as a model.

The Hoover Institution's California Decides 'Proposition Lab' guide to Prop. 4 covers quick facts, key legal language, who is involved, trade-offs, potential risks and benefits, and open questions.

• Hoover says the measure lifts the 1988 Proposition 73 ban and lets the state, counties, and general-law cities create programs, which charter cities can already do.
• It quotes the key text of Section 85300(a) (earmarked funds) and 85300(b) (expenditure limits and strict criteria).
• It lists SB 42's authors (Umberg, with Ben Allen and Alex Lee) and the vote (Assembly 59-20, Senate concurrence 29-8), and says the governor signed it October 2, 2025.
• It describes the evidence that public financing reduces corruption as 'genuinely mixed', and says that depending on design programs can favor incumbents.
• Benefits it lists include ending an inconsistency with charter cities and building in guardrails; risks include open-ended fiscal effects and leaving key choices to future legislation.

The California Clean Money Campaign's Yes on Prop 4 page (paid for by the California Clean Money Action Fund). It urges a yes vote, lists endorsers, and reviews the group's earlier campaign-disclosure legislation, including its sponsorship of SB 1107 (2016), an earlier attempt to allow public financing.

• The group says more than $1 billion has been spent on California state candidate races since 2020.
• It says Prop 4 would let communities set up public funding systems so candidates can compete against corporate special interests and billionaires.
• Listed endorsers include the League of Women Voters of California, California Nurses Association, California Federation of Teachers, ACLU California, California Common Cause, California Environmental Voters, and Indivisible CA: Statestrong.
• The page describes SB 42 (Umberg-Allen-Lee) as putting the California Fair Elections Act on the November 2026 ballot.

The California Taxpayers Association's analysis of Proposition 4 recommends a no vote. It sets out the group's reading of the measure's provisions, fiscal impact, legal background, and policy concerns.

• CalTax argues the measure would let politicians spend tax dollars on campaign mailers and ads instead of public services.
• It says that under campaign finance law a person becomes a 'candidate' upon filing a notice of intent, so funds could reach people who never qualify for the ballot.
• It notes that the FPPC would not enforce local programs and argues that this leaves them open to inconsistent enforcement and fraud.
• It says the measure lets all local governments, including more than 3,000 special districts, create programs, and could fund races for county party central committees.
• It describes the $10 counting rule, the 'net supportive funds' formula for raising spending limits, and the higher penalties on foreign contributions (from equal to the amount up to three times the amount).

A Spectrum News 1 Los Angeles story by Chace Beech on Prop. 4, with a supporter (California Clean Money Campaign) and an opponent (strategist Mike Madrid) and a description of Los Angeles's matching funds program.

• Trent Lange of the California Clean Money Campaign says the measure gives communities the option of small-donor public financing.
• Mike Madrid, a fellow at the USC Center for the Political Future, opposes it and says the money should go to government services.
• The story says Los Angeles matches donations of up to $257 for citywide candidates at a 6:1 rate, and that participation is voluntary.
• It notes that the measure would not require cities to create programs, and that campaign money could not come from education, transportation, or public safety funds.

A California Globe republication of the Howard Jarvis Taxpayers Association's 2026 voting guide. It recommends no on Prop. 4 along with HJTA's positions on other measures and its PAC's candidate endorsements.

• HJTA says Prop. 4 would remove the Political Reform Act ban on using tax money to finance campaigns for elective office.
• HJTA opposes taxpayer-funded campaign expenses and recommends a no vote.
• The rest of the guide covers other propositions, local tax measures, and candidate endorsements.

A CalMatters explainer by Yue Stella Yu on whether Prop. 4 would curb money in politics. It covers the 1988 ban's history, both sides' arguments, research on public financing, editorial positions, and polling.

• CalMatters reports that seven charter cities, including San Francisco, Berkeley, and Oakland, already have public financing, and that voters rejected similar measures in 2000 and 2010.
• Supporters quoted include Trent Lange (California Clean Money Campaign), Sen. Tom Umberg, and Dora Rose (League of Women Voters of California); Gov. Newsom and the Legislature support the measure.
• Opponents quoted include Assemblymember Carl DeMaio; the San Francisco Chronicle and San Diego Union-Tribune editorial boards are cited as opposed.
• CalMatters reports that research on effectiveness is mixed: studies of Seattle, Arizona, and Maine found more candidates or competition, while a 2010 GAO report found no such evidence.
• Polling: a September PPIC poll had 42% yes and 53% no among likely voters; a UC Berkeley IGS poll had 35% to 35%.

A transcript of KQED's 'Prop Fest' podcast episode in which reporter Izzy Bloom explains Prop. 4: the 1988 Prop 73 history, how the measure works, examples of existing programs, and supporters and opponents.

• Bloom says Prop 73 also set contribution limits that a federal judge later threw out, leaving the public financing ban.
• Bloom says the measure lets the Legislature amend the mechanics and eligibility rules of public financing without another vote of the people.
• Bloom describes San Francisco's program as an example: a mayoral candidate can receive up to $1.2 million, must show qualifying contributions, face an opponent raising or spending at least $50,000, and accept a spending limit.
• Supporters named: California Democratic Party, California Common Cause, League of Women Voters of California, California Clean Money Campaign. Opponents named: CalTax, HJTA, Reform California, and former FPPC Chair Dan Schnur.
• Bloom reports that spending on the measure was minimal: $7,500 in opposition from Reform California.

A Ballotpedia News article by Victoria Antram from when SB 42 was signed. It explains the measure, the history of Proposition 73 and SB 1107, and SB 42's contingent foreign-contribution provisions.

• Ballotpedia says the measure would let the Legislature amend the public-funding provisions without voter approval but would require voter approval for other provisions.
• Ballotpedia reports that SB 42's foreign-contribution provisions would have operated only if AB 953 did not pass; Gov. Newsom signed AB 953 on Oct. 1, 2025.
• It describes three common models of public financing: matching funds, vouchers, and grants. It says 15 states and D.C. have some form for state offices.
• SB 42 passed along party lines; endorsers in the legislative process included the California Democratic Party, ACLU of California, California Common Cause, Consumer Watchdog, End Citizens United, and Represent.Us.
