Californians this fall will decide whether to require voters to show proof of citizenship before casting ballots.
A GOP-backed voter ID ballot initiative on Friday qualified for the Nov. 3 ballot,marking a significant win for San Diego Assemblymember Carl DeMaio, who led the signature-gathering campaign. DeMaio and other Republican operatives have pushed for tighter voter restrictions in deep-blue California for years.
If voters approve it, they would be required to show a government-issued ID each time they go to the polls, while mail-in ballots would need the last-four digits of an ID, such as a driver’s license. The secretary of state and county election offices would also be required to verify voters’ registration each time they vote.
Currently, voters only need to provide an ID and Social Security number when they register to vote. Thirty-six states require or recommend voters show some form of identification at the polls, according to a 2025 report by the National Conference of State Legislatures.
“This is an initiative that’s incredibly popular amongst Democrats and Republicans,” GOP state Sen. Tony Strickland of Huntington Beach told CalMatters. “I think the only way we don’t get this passed is if we get (outspent). So we’re working very hard with an on-the-ground campaign apparatus.”
Strickland and others who have helped lead the campaign attribute the initiative’s rapid certification to Julie Luckey, mother of tech billionaire Palmer Luckey who helped seed the majority of the $10 million the campaign committee has raised in the past year.
Voting rights groups say the initiative will suppress turnout among eligible voters who don’t have the documents on hand, many of whom are disproportionately poor and people of color.
Opponents, including the state’s most powerful labor unions, plan to campaign heavily against it.
Voter fraud is rare in California. However, claims of fraud and concerns about election integrity have risen since President Donald Trump touted false claims that the 2020 election was stolen.
Californians broadly support voter identification at the polls but are split along ideological lines when given specific details about the ballot measure, according to a 2026 poll from the UC Berkeley Institute of Government Studies. When told the measure is meant to combat voter fraud and that it could suppress eligible votes, support dipped to 37%.
