This reminds me of an effective technique for hacking an election: keeping the people who would vote against you from coming out to vote at all. For example, by threatening a law and order crackdown in the area. Busting people for minor traffic infractions, checking if they have outstanding warrants, etc. This is greatly facilitated by per-booth vote tallies, and pushing people to use a local booth. It might be that electronic voting would allow voting from many places, and hence alleviate the problem. But I'm guessing there will still be restriction of polling booth locations to make it inconvenient for some people to vote.
