Next round we need a watermark or other unique identifier on all ballots; something that can't be faked.
We are one of the most technologically advanced countries and we can’t get voting right. Ridiculous. Just spend the extra money to have a counting machine in each precinct. A Republican and a Democrat on each side. Once you mark your ballot and they mark it off you walk to the machine and feed the ballot into it and it shows your votes/results. The totals could be sent directly to the county elections board as they happen. All mail in ballots could be tallied at the elections office the day of voting.
It’s really not that friggen hard. The problem is it would cut out most of the cheating.
