Why does Bob Casey have a 12 point lead over Tom Smith and Barack Obama only has a 6 point lead over Mitt Romney? Idiots, that’s why!
Look people, you’re overthinking this. Despite there being a bunch of names on the ballot, there are only two choices. The Democrats or the Republicans. Make the choice, and then vote for all that party’s candidates. Voting for one party’s Presidential candidate and then cancelling that vote out by choosing a different party’s Senate or House candidate makes zero sense!
Decide which party you think is more right, and then vote a straight ticket.
