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

As I understand it, a fairly bulletproof method is to vote using a machine that prints out a human readable card with a punch through the candidates you voted for. So you can confirm the machine understood the options you tapped and then drop the paper ballot into a secure box, which can be used as a backup for manual recounts.
Anybody know if this is what the experts [still] want?
