  • When setting voting rules, which should come first?

    The official text says a YES vote moves toward: Making sure only eligible people vote, and each votes only once.

    The official guide says a YES vote means: "Voters would be required to present additional identifying information to elections officials each time they vote."

What the Legislative Analyst says

Requires State and Local Elections Officials to Verify U.S. Citizenship Status of Registered Voters. Proposition 39 requires state and local elections officials to make “best efforts” using government data to verify that voters on the rolls are U.S. citizens. Proposition 39 requires elections officials to report every year the percentage of registered voters in each county whose citizenship status has been verified. Requires Voters to Select Government- Issued Identification for Voting by Mail. Proposition 39 requires new and existing voters to select a government-issued identification in their voter registration to vote by mail.

Fiscal effect

State and local government costs of between tens of millions of dollars and low hundreds of millions of dollars each year to implement new voting requirements. Costs depend on future decisions by the Legislature, state departments, local governments, and voters.

Missing context

Official argument in favor of Proposition 39

“Voters can use a variety of easily-obtained government IDs to vote—and this measure even guarantees every voter a FREE Voter ID if they want one.”

The Analyst says the measure requires the state to provide a voter identification card at no cost to voters who request one, usable as the government-issued identification for verification. The Analyst also says Proposition 39 requires the Legislature to pass additional laws and would need to clarify details not defined in the proposition, "like which forms of identification could be used", so the variety of IDs the argument describes is not established in the guide. "Easily-obtained" is a characterization the guide does not address.

Not supported

Official argument in favor of Proposition 39

“In the last election, more than 100,000 ballots were rejected due to signature mismatches—and more than 200,000 voters endured hassles just to get their vote to count.”

The guide does not say which election is meant. Secretary of State rejection-reason reports give these figures. June 2, 2026 primary: 148,427 mail ballots rejected, 93,666 of them late and 43,976 for non-matching signatures. November 4, 2025 statewide special election: 159,999 rejected, 72,473 late, 69,171 non-matching signatures. November 5, 2024 general election: 122,480 rejected, 71,381 non-matching signatures. In each election total rejections exceeded 100,000, but signature mismatches alone were under 100,000, so the figures do not support "more than 100,000 ballots were rejected due to signature mismatches". The claim that more than 200,000 voters endured hassles is not documented in the guide or in these reports.

Missing context

Official argument against Proposition 39

“Prop. 39 will make every vote by mail voter include their personal details on their return envelope—making voters easy targets for identity theft.”

The Attorney General's summary and the Analyst say mail voters would write the last four digits of a government-issued identification number on the ballot envelope, matching the number in their registration. The guide does not describe other personal details being added or assess identity-theft risk.

Supported

Official argument against Proposition 39

“Get one digit wrong, and a valid ballot could get thrown out.”

The Attorney General's summary says mail ballots would be invalid if the envelope does not include the last four digits of a government-issued identification number matching the number designated in the voter's registration, and gives an example of a ballot that would not count.
