For regular ballots all people showing up at the polls would have to be identified with their thumb print or any other finger of their choice.
The finger of choice would have been established well before the election and could be changed between elections.
This might not eliminate voter fraud but it would cut it down. Also, we need all electronic ballots and only machine counting, no hand counting allowed. This would cut down on the "finding" of ballot boxes during the count, which, as we all know, is an old democrat trick still being used effectively by them today.
Yeah, that's what we should do - fingerprint everyone at birth and put locks with fingerprint scanners on them on all public and private buildings and at every cash register in the country. Yeah, that's it.
