It’s completely normal that in 20h time period the counted duplicate ballots were casted ONLY for one candidate, which happened to be Biden.
It’s completely normal for poll workers to change challenged ballots to a straight Democrat ticket by filling up the ballots by themselves.
It’s completely normal to add votes from the same batch multiple times.
It’s completely normal to have poll center boarded up and not allowing GOP poll watches back in.
If you say that all looks like an election fraud you are conspiracy theorist.
