“Who do you suppose they voted for?”
If they voted, they broke the law and should be prosecuted.
Even by representing themselves as someone else at the polling station would be against the law.
They didn’t vote. They didn’t claim to be the dead people in question. They just asked if the name was on the list and they were given a ballot and told that they didn’t need to provide ID.
By watching the video, you will see that they took care not to misrepresent themselves and not to vote.
I’d lay money that most of them voted for Romney and many for Huntsman.
