For the zero’s and ones, can’t some group of Romney voters sign affidavits that they voted and for Romney, and see their names crossed off the voting list? There must at least be a party affiliation list for those that voted.
Just pick a few zero vote precincts and advertise to see if anyone voted for Romney. They’ll publicly admit it just like they do when a murder is committed.
Better just to compare each of these precincts to McCain ‘08 votes.
