I just voted for Mitt in Cambria county PA. The crowd was large for a small town precinct like ours. We have never had to wait in line to vote until today. Other than one guy complaining that "a sitting president was second on the ballot" the you couldn't tell if the crowd was pro either candidate. Logically you have to think it was pro Romney due to geography but I have no evidence to back up my assertion.
So there is your dose of anecdotal evidence for small town western PA. I have a good feeling about tonight.
