The answer may surprise you. According to the San Diego Union Tribune: “When it comes to mail ballots, it’s not fraud that vexes election officials. It’s human nature. People procrastinate. That’s a problem as California prepares amid the COVID-19 pandemic to mail a ballot to every registered voter in the state for November’s presidential election.
“The ballots go out the week of October 5 and have to be returned by Election Day, November 3. Some people who wait until the last minute think that means they’re OK if they put it in a mailbox on that date. But that’s not the rule. Ballots have to be postmarked by Election Day, and they have to arrive no later than 17 days after that date at the county Registrar of Voters office or they won’t get counted.
During the March primary, this was by far the most-common reason mail ballots got rejected in San Diego County and throughout the state. They arrived too late.”
