Count me skeptical. If something was really amiss, we would have heard about it. I suspect the registration numbers are dated. The Pubbies had a heavy ground game in Ohio, which nosey Pubbies in all the suspect precincts. If there was massive fraud, we would have heard about it. It does seem Detroit manufactured some votes, but then Michigan wasn't really in the Bush lense, and thankfully, the Detroit thing almost certainly did not swing that state.
OK, but look at post 91. Oakwood Village has not doubled it's population since 2000. The number of votes is double the entire population of the town!
