I'd partially filled out my ballot a few days ago, but tonight I finished it: checking endorsements and reading the voters' guide. Some difficult choices, but I feel okay about my choices.
Next is dropping it off. It's too late for me to mail it, so I can go to either a county library — the book return slots that aren't being used for books at the moment are being used instead for ballots — or to a County Elections drop box, which I'd prefer to do this time. So I'll be driving at least once between now and Tuesday at 8:00 p.m., the latest I can drop it off. I'll drop it off sooner than that.
Meanwhile: Vote-by-mail. Good.
