Anyone registered in more than one state and voting in more than one state probably committed voting fraud.
It's not probably it's “they did!” But the issue of being registered at more that one precinct ( or state ) is likely this nonsense that you “stay registered” even if you don't vote. Our daughter and her husband lived with us for a short period of time when they returned from Japan where they had expat jobs. It took FIFTEEN years to get our county to remove them from the rolls here, and the have lived in another county here in the SF Bay Area since they moved from our home. It's like the woman in the earlier post with a demented mom, you have to remove yourself from the rolls, otherwise you stay on forever. This is really just another one of the illegal artifices that the RAT Party has used in it's quest for one-party rule in America, because there do not appear to be any safeguards to someone else “voting” these registrations surreptitiously.
