To Protect the Election Process & the Votes of all Voters in the Future from Voter Fraud & Election Fraud, as Well As Preventing People from Voting repeatedly, more than once, require a Thumb print be put on all Future Absentee ballots used to cast a person's vote.
Also everyone who votes at a Voting/Polling Location should be stamped with the words, "I VOTED" with ink that cannot be washed off for at least 24 hours so that person can not go to another voting booth to vote again or stand in line to vote as another person repeatedly.
Stamp OUT VOTER & ELECTION FRAUD. Other Countries use ink to mark when a person has already voted to protect repeated votes by the same person. No harm is done and the votes of all is protected! "I VOTED" is Patriotic and lets others know You already VOTED!
