Of course, it’s in Illinois (reformatted, emphasis mine)!
Early voting in Illinois got off to a rocky start Monday, as votes being cast for Republican candidates were transformed into votes for Democrats. Republican state representative candidate Jim Moynihan went to vote Monday at the Schaumburg Public Library. “I tried to cast a vote for myself and instead it cast the vote for my opponent,” Moynihan said. “You could imagine my surprise as the same thing happened with a number of races when I tried to vote for a Republican and the machine registered a vote for a Democrat.”
Hmm, it was explained that it was a “simple” calibration error. Ayup, sure thing. Curious thing, though – it seems this “machine flu” was caught in Amarillo, Texas, too (reformatted, emphasis mine):
…It’s not as common to see the stories I’ve been seeing today. Two voters from Canyon posted the experience they had while voting. Apparently, when these voters chose the straight Republican option, the ballot selected Clinton/Kaine instead of Trump/Pence. The same story has been reported in Dallas.
