Every mail in must have a valid registered voter signature, and the registered voters are classified as D or R or I. Every person showing up at a precinct to vote must be on a registry for that precinct, as either D or R or I. Compare the mail in ballots to registered votes at precinct and if there is an overlap of the name remove two votes for the registered D or R or I.
Isd it an wonder why the demon rats screamed so foul when the signatures were to be required to match? Is it any wonder why the demon rats demanded mail-in balloting and demand after the election day submitted ballots be counted?

I see your point but too many states have you finger sign on a tablet. If what I signed yesterday were compared to past signatures I would be arrested. Finger signatures have all but invalidated the very idea of signature as ID in too many venues.
