Californians love mail-in voting. That may have to change come November

Californians widely use mail-in voting, but potential changes from a U.S. Supreme Court ruling and a U.S. Postal Service policy shift could affect how ballots are processed in November. A Supreme Court decision in Watson v. Republican National Committee may eliminate grace periods for late-arriving mail-in ballots, impacting states like California, where 2.5% of votes in 2024 arrived during the seven-day grace period.
