That last bit sounds like ubran legendy in the making.
We used Ivotronic machines here in central NC. The process seemed smooth, but I have no idea whether the vote I cast was recorded correctly.
It didn't sound like it shredded to me when I cast my vote, but someone else came into the office this afternoon and said thats what the machine did. That is why I am asking. It would make NO sense to shred ballots.
