I’m from New Jersey and at my polling place, once the little old lady finds my name in the big book, she gives me a slip of paper with a serial number on it, which I hand to the lady at the entrance to the booth before I enter to vote. I always think “They can see my vote by simply going back and seeing how serial number #@%$#& voted.” Or am I being paranoid?
Hmmm... I never paid close attention to that little slip of paper, so I don’t know.
Maybe someone else here knows more about it.
