Part of that recount should be a random 10% of mail in or drop box ballots cast be verified by an in person door to door interview affirming that that was the ballot cast and by said person?
You can’t know what person cast what ballot, all that is tracked is who cast a ballot and what method, in person or mail/absentee, still be effective.
In PA, 2 options, 1) if the counties don’t have a number of ballots cast equal to the number of names who cast a ballot, that is fraud which is then 2) proven by random sampling of people who are marked as having cast a ballot. You start by sampling people over 90 years old, since your voter registration includes your birth date, and so on. That takes resources that someone has to pay for and perhaps some cooperation from the county. This is how you find the 700000 vote lead that vanished in PA after election day. Election fraud is very easy and I always wondered why the dems didn’t perfect it earlier. It doesn’t take hacking machines and all that nonsense. As long as there is a paper ballot and the counties continue to track voter history it can be proven. The purpose of tracking voter history is to target voters by the political parties, which is why the dems require it too. I fear soon they will do away with tracking voter history and paper ballots so there is no way to prove fraud.
