Proposition 39, a ballot initiative set to appear before California voters this November, aims to implement new requirements for verifying voter identification and citizenship. The proposal mandates that election officials must verify the identification of individuals casting a ballot, including confirming that registered voters are U.S. citizens.

Supporters of Proposition 39 describe it as a common-sense measure to enhance election integrity. They assert that current laws, which already prohibit noncitizens from voting, are difficult to enforce in practice. The proposition would shift the burden to state and local election officials to verify the citizenship of registered voters and report the percentage of verified citizens on the rolls.

Under the proposed measure, in-person voters would be required to present government-issued identification. For mail-in voting, which constitutes the majority of ballots cast in California, voters would provide the last four digits of a government-issued identification number of their choice. The initiative also states that the state would provide a free voter identification card upon request for eligible voters who need one.

According to proponents, similar voter identification requirements are already in place in 19 other states, affecting nearly half of the U.S. population. They also cite public opinion polls, such as a Gallup poll indicating that 84% of Americans support requiring photo ID to vote and 83% support requiring proof of citizenship for first-time registrants.

Arguments against voter ID laws, which opponents claim create barriers to voting and disproportionately affect minority voters, are refuted by supporters. They point to research, including a randomized field experiment conducted by the Abdul Latif Jameel Poverty Action Lab, which reportedly found that voter ID notifications did not reduce turnout and may have increased participation among certain voter groups. Additional research cited suggests that voter ID laws have no significant aggregate effect on turnout.

Proponents argue that these measures can strengthen public confidence in elections without diminishing participation among eligible voters. They also highlight past instances where state political actions have sought to prevent local voter ID requirements, such as legislation passed after Huntington Beach voters approved a measure for municipal elections. Proposition 39, they contend, offers voters statewide a direct opportunity to decide on such measures.

The initiative leaves specific details, such as which forms of government-issued identification will be accepted, to the Legislature to determine. Supporters maintain that this allows for fair consideration of all relevant factors by lawmakers.
