This is no big deal. A provisional ballot only counts when it is validated by Board of Elections after the election as a legit vote. When people see what is involved in casting a provisional ballot most will opt to go the correct pct. If they have moved and not told the BOE then they have to vote provisional. It will only be counted IF they were registered somewhere in the state and only those races and issues also on the ballot where they now live will be counted if they vote anywhere else. I am glad I am not the one to review the prov. ballots. This is how it is in MD.
Yeah, the provisional ballots are a pain in the butt for the resolution board who has to sort them out. To actually force this kind of thing really isn't that good for the Democrats, because you would quickly catch on to a pattern of illegal voting.
The worst case would be a Dem dominated county, at least here in Iowa the county in the majority has the majority on the resolution board. You would likely then be outvoted in a Dem county, meaning a court fight, which is expensive and the decsion comes long after the election.
