In Raleigh NC the paper ballot has a code on top that is matched to the voters info would be fairly easy to get the ballot coded to the voter and destroy the fraudulent one. They have to have some means of identifying ballots. They darn sure can tell if you vote with one party or the other.
Shows why dimwits like early voting-get there before the real registered voter.
Yes, for the primary. But, not for the general election.
