A California friend of mine said he'd already received his mail-in ballot and had no idea how they were going to handle this situation. Then he went on a rant about how he had somehow gotten signed up years ago for mail-in balloting and if he voted in person his ballot would be "provisional." He said he was pretty sure he never signed up for mail-in and had tried to get out of it a couple of times but can't seem to. Next time I talk to him I'll ask him about the names on the ballot.
