This happened in Roanoke, which is left leaning. Republicans are going all out to cheat in this election.
Edit: Here is the law on tampering with ballots in Virginia. Class 5 felony

in my state (OR) you can sign up for an email that says when your ballot was counted but not who you voted for.
Yeah there is a good reason for that to be secret: it prevents buying votes because you can’t prove who you votes for, if someone offers you money to vote a certain way you can always take the money and vote the other way, no way to prove how you voted.
