Yes, the print out goes straight to the voter to turn in. If the machine changed their vote, you think they wouldn't have told anyone? Yet we are still where we were when you started this crap... zero actual evidence.
Exactly. If there was some sort of mass fraud, a lot of people would have noticed that their votes had changed. And it would be pretty risky (and dumb) for anyone to risk doing such a scam and think several thousand people people would not notice when they turned in their ballots.
