Doesn't matter. Voter ID nuts will still state South Carolina's "fraud" as fact. They have never let truth jor logic get in the way before, so why start now.
Not trying to be a doubting thomas here but there is fraud that is on purpose and there is fraud committed by accident. My polling place chaned a few times while I lived in Texas because I was re-districted into another district. I wasn't commiting fraud but I was in a booth where I didn't belong, casting a ballot. If you were to examine that election, my ballot should have been thrown out.
But let's say that the line I crossed over wasn't a redistricting line but one of city limits. We lived in Houston but two or three blocks away was another city. City ordinances would be on the ballot often; just as they are in Phoenix now. If you live in Glendale or Tucson or Paradise Valley or Tempe, the Phoenix ordinances don't affect you. If you're going to the wrong polling place, you could be voting on ordinances that you should be disallowed from; the folks in Tempe shouldn't be voting to increase the Phoenix city sales tax for example.
I would wager that several people show up at the polling place ignorant of whether it is the "official" polling location or not and are given a ballot that is improper. Since Brewer and McCain and/or Flake are on the ballot, they cast the ballot but down ballot, there are judges, referendums, propositions, etc...
Should people in Ohio be able to vote in Pennsylvania? I don't think so. I would like to have as much assurance as possible that it isn't happening.
