I moved to vote-by-mail because of the insecurity of electronic voting. However, I always drop off my ballot on election day. I guess it's a thing I really like, actually voting on the day of the election. And the irony is that apparently a lot of other people do too, because they personally bring in their envelopes, and now we've gone to paper ballots again. Sometimes people come in and surrender their vote-by-mail ballot and actually vote. It's a rather interesting phenomenon.
But having polls that are mostly used for that purpose is inefficient. Either we move to mail only, or we need to rethink the whole system...
