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

The majority of votes in the USA are electronically counted, and a ballot itself is a record of a vote as well. What there isn’t is a searchable index of who voted for what, and I apologize for my unclear language.
But the likelihood of oppression based on availability of those vote records is still very much there even if the voter themself doesn’t have access.
Back to school. Vote-buying breaks democracy. Not having proof of who you voted for makes vote-buying pointless. Yes, your vote could be miscounted. This is generally less of a problem than the general population being able to sell their votes and can be mitigated in a variety of ways which don’t tie votes to voters.
