— Elon Musk (@elonmusk) January 12, 2026 In California the biggest impact of the voter ID measure would be a provision that requires voters who mail in their ballot to include the last four digits of their ID number. More than 80% of votes cast in the 2024 election in California were mailed in — compared with about 29% nationwide. The majority of voters in California cast a ballot by mail, rather than going to the polls. Getty Images Stephen Richer — the former Maricopa County Recorder in Arizona who was in charge of voter registration and early voting — said he is concerned that the vote-by-mail ID provision could discourage some people from sending in their ballots. Richer said getting people to support putting sensitive information in the mail could be a “little more complicated.” “Simply showing a photo ID to vote in person, polls very well across the American political spectrum,” Richer said. “If you start putting other things on it, like in Maine, they just ran a voter ID campaign that lost in the most recent election, because they had other stuff pertaining to mail ballot voting that wasn’t nearly as popular.” Coinbase CEO Brian Armstrong threw his support behind the ballot measure, calling it an “important foundation for democracy.” AFP via Getty Images
