Thanks! I was somewhat worried about putting my ballot in my mailbox instead of a ballot collection box specifically because of a fear of this. But ultimately I decided that I live pretty far from areas where that may happen, I put the ballot in right before bed so it could be picked up first thing in the morning, and I decided that even if it got stolen, it wouldn’t matter all that much since my state is heavily blue.
I saw some campaign points against it, and they said “it’s too confusing”. Political messages these days basically rely upon people being stupid and lazy.
