Or printing a few thousand more ballots...
Or double counting a few thousand...
I don't know about anyone else here, but where I live the vote is NOT that evenly split.
Granted, my circle of acquaintances is relatively small, but those I talk with aren't evenly split, either.
My results may not be representative of the rest of the country, but from the first polls we are told that the ratio of sane to insane people is set close, but from the people I speak with, that's just wrong. It is nowhere close.
