Excerpts:
Elections officials around California rejected 122,480 vote-by-mail ballots cast during the November general election, or 0.9% of all mail-in ballots, according to data from the Secretary of State’s office.
The vast majority of those arrived late, had mismatched voter signatures or no signature at all.
Elections officials are supposed to notify a voter if their mail-in ballot has a signature issue and provide an opportunity to “cure,” or fix it. But they’re not always successful, leaving those ballots uncounted. They are kept for 22 months, as are all ballots cast.
An analysis of mail ballot rejections during the 2024 election by USC’s Center for Inclusive Democracy found that 59% had a non-matching voter signature, 27% were mailed or arrived after the deadline, and 11% had no signature. The other 3% were dismissed for other unspecified reasons.
