Challenges in California’s Mail-In Voting System

In California’s June primary, nearly 150,000 mail-in ballots were rejected, a noticeable increase from previous elections. This uptick comes as the state aims to enhance voting accessibility to improve participation and ensure all ballots are counted.

Mail-In Ballot Timing Issues

California’s slow vote counts stem from efforts to increase turnout, including allowing a week’s grace period for ballots postmarked by Election Day. However, the main reason for rejection remains late-arriving ballots. Most of these had postmarks dated after Election Day, impacted potentially by changes at the U.S. Postal Service.

Data from the secretary of state’s office shows 148,241 mail ballots were rejected in June, equating to a 1.73% rejection rate. Previous years saw fewer rejections, with 108,982 in the 2024 primary and 105,818 in the 2022 primary. A significant 93,479 ballots were dismissed for lateness in the recent primary.

“Ballots rejected due to lateness primarily result from being postmarked too late, not arriving too late,” commented Kim Alexander, president of the California Voter Foundation.

Concerns Over Postal Service Changes

In response to these issues, U.S. senators, predominantly Democrats, expressed concern that USPS procedural modifications might impact postmark dates, potentially affecting election outcomes. Current policies suggest postmarks may not reflect the initial reception date but rather the processing center handling date. Consolidations in the Postal Service could further delay postmarks.

Wisconsin Democrats have urged the Postal Service to address these concerns following similar issues in April where ballots arrived after Election Day. In California, local election officials advised voters to send ballots early due to potential mail service delays.

Breaking Down Rejection Reasons

Rejection rates were highest in Tulare County at 3.52%, followed by Alpine and Merced counties at 3.36%. Besides lateness, over 44,000 ballots were discarded due to mismatched signatures, while 8,300 lacked a signature altogether. Some ballots were voided for duplicates or absence of the ballot in the return envelope. Instances of mail voting fraud are extremely rare, as a Brookings Institution report indicated only four cases per 10 million mail ballots.

Comparisons and Political Responses

Unlike Florida and Texas, where vote counting concludes swiftly, California experiences prolonged delays. Following the June primary, President Donald Trump criticized California’s pace, and a DOJ investigation into Los Angeles County’s elections ensued. Despite these challenges, mail voting remains popular across party lines.
