Now I wonder, “Why the heck don’t I do that?”
We should make a ballot to end the ballot
Matt Trainer

Vote-by-mail is done very well, it’s a no-brainer:

Done early? Mail it in.

Done late? Drop it off at any poling station on election day, or City Hall up to a week before.

Too late? Surrender your mail-by-vote packet at any poling station and get an in-person ballot.

It should be the default when you register to vote in SF.
