Arizona (Maricopa County) was printing 19″ image ballots and the tabulators were programmed to scan 20″ ballots. That was the cheat that broke the Maricopa County voting centers on Election Day.
The sitebooks (check in for voters) in Maricopa County gave Democrats the 20″ ballot that could be read by tabulators and Republicans 19″ ballots that COULD NOT be read by the tabulators. Holy smokes! Team Kari has the goods!
