It's going to be a cluster fuck for those states sending out unsolicited mail-in ballots. It should be by request only. I still think they should have separate rolls for whatever method is chosen, and have it be a one-to-one relationship instead of one-to-many. If a state chooses to send unsolicited mail-in ballots to every person, then nobody should be able to vote in person--this would be assuming a "perfect system", which is much different than the actual current scenario.
