# Prop 4: Allows public financing of political campaigns

URL: https://www.californiapeople.org/props/prop-4

- number: 4
- title: Allows public financing of political campaigns
- type: Legislative measure (SB 42, Umberg)
- sponsor: Legislature

**Our read: Lean no.** Lets the state and any city or county spend tax money on political campaigns, with no further vote by you. The best-studied program didn’t broaden who donates.

## Key findings
- It repeals the 1988 ban (Prop 73) on spending public money on candidates' campaigns. It creates no program itself, but **afterward the Legislature, any city council or any county board could create one by statute, ordinance or charter, with no further vote of the people**. [^1][^2]
- **The guardrails can be loosened later without you.** The ban and its replacement rules sit in the Political Reform Act, which the Legislature can amend by a **two-thirds vote** if it finds the change "furthers the purposes" of the act. A statute, ordinance or charter can also raise a program's spending limits, within a formula. [^3][^2]
- Rules a program must follow: candidates must show "broad-based support" through contributions or vouchers of **$10 or less**, accept voluntary spending limits, and can't use the money for legal fees, fines or repaying their own loans. Money earmarked for schools, transportation or public safety is off-limits, but **general-fund money isn't**. [^2][^1]
- Only **five California cities** (including San Francisco and Berkeley) have public financing today. [^4]
- **The best-studied program, Seattle's $100 "democracy vouchers," did not diversify the donor pool.** The voters it mobilized were mostly those already overrepresented among donors. [^5][^6]
- **Yes $984.6K, No $0.** Top donors are the Yes on 4 committee and Movement Voter PAC. [^7]

## Track record
| Program | Model | Evidence |
|---|---|---|
| Prop 73 (1988) | Banned public financing for most state and local offices | Some charter cities are exempt and run programs [^1] |
| San Francisco, Berkeley, others | Matching funds or vouchers | 5 cities statewide [^4] |
| Seattle | Four $25 vouchers per voter | No improvement in donor diversity by race, income, age or party [^6] |
| **Prop 4 (2026)** | Allows programs statewide | Effect depends on what gets built later |

## What it does
- Lets the state and local governments create public financing if they choose. It can't use money earmarked for education, transportation or public safety. [^4]
- Cost: a few hundred thousand dollars a year, mostly for the FPPC. [^1]

## Money and conflicts
- Author Sen. Tom Umberg [^8] also filed to run for the Board of Equalization (District 4) this year. [^9] Incumbent legislators would write any state program.
- Taxpayers would pay for any program, including for candidates they oppose.

## Does it solve a lasting problem?
- Big-money influence is real. But the strongest evidence, from Seattle, shows public financing didn't change who funds politics, and once the ban is gone, programs can be created and grown by the officials who benefit from them, with no vote of the people. [^6][^2]

## If you vote yes: accountability
**Bottom line:** Prop 4 creates no program, so the accountability fight comes later, when a city, county or the state actually designs one. [^1]

### Who decides
- **The Legislature** for any state program, and **city councils and county boards** for local ones. In Rancho Cucamonga, that's the City Council.
- **The FPPC** (Fair Political Practices Commission) would carry most of the state's administrative cost. [^1]

### What to ask for in any program
- **Public lists** of every candidate who gets public money, how much, and what they spent it on.
- **A random audit** of each campaign that receives public funds, with clawbacks for misuse.
- **Published results**, so voters can tell if the program changed who gives and who runs. Seattle's voucher program did not diversify its donors. [^6]
- **No money from funds earmarked for schools, transportation or public safety.** The measure already bars that. [^4]

### Public records to request (CPRA)
Anyone can file a California Public Records Act request (the state's version of FOIA), with no reason required. Agencies must respond within 10 days, or 24 in unusual cases. [^10] Once a program exists, ask the agency running it for its payment records and audit files. Candidates' campaign filings are already public through the Secretary of State and local clerks.

## Both sides
- **For:** Common Cause, Clean Money Campaign, League of Women Voters, CA Democratic Party, Sacramento Bee. It helps small donors and new candidates compete. [^7]
- **Against:** CalTax, HJTA, Reform California, Hispanic Chambers, former FPPC chair Dan Schnur, SF Chronicle, OC Register, SD Union-Tribune. Taxpayers would pay for campaigns, with no spending limits. [^7]

## Official voter guide (condensed) with annotations
- Official title: Repeals Prohibition Against Public Funding of Election Campaigns. Legislative Statute.
- Summary: Repeals the ban on state and local governments offering public funding to candidates. Programs could not use money earmarked for education, transportation or public safety.
- Fiscal impact: A few hundred thousand dollars a year for the Fair Political Practices Commission.
- A YES vote means: State and local governments could create public campaign financing programs, subject to limits on which public funds could be used and who could receive them.
- A NO vote means: The state and most local governments would remain unable to create public campaign finance programs.
- Argument for: California is the only state that bans public campaign funding. Removes the ban with "strict taxpayer safeguards." Special interests want to keep the ban.
- Argument against: Lets politicians use taxpayer money for negative campaigns, with "NO LIMIT on the number of candidates who can get taxpayer money."

- Opponents: California Taxpayers Association, Howard Jarvis Taxpayers Association, Family Business Association of CA

Annotations (what the booklet leaves out):
- (summary) This creates no program by itself. It only lets governments create one later. Five California cities, including Berkeley and San Francisco, already have public financing. [^4]
- (con) Prop 4 itself funds no one. Any actual program, including how many candidates qualify and for how much, would be set later by the state or a local government. [^1][^4]
- (general) Author Sen. Tom Umberg is also on your ballot, running for Board of Equalization District 4 (if you're in that district). Research on whether public financing works is mixed. [^4]
