There is also a remote chance of a 269-269 tie in the Electoral College. In which case, the likely Republican congress would pick the winner (there might even be a two party split between the President and Vice-president, something not seen since the 19th century).
I’m from New Hampshire. I voted for Ron Paul in the primary. A lot of people did. I voted for Perot twice. A lot of people did. We know Romney well and I think he will take New Hampshire. Romney is not like Bush 41, Dole, or McCain. He is a man applying for a job. Once we elect him, Romney will accept and act on his mandate.
There are two reasons I vote for a candidate: 1) I like what he says, and 2) I believe he will do what he said. I like what Romney is saying and believe he will execute once elected. For this reason, he gets my vote. For this reason, he wins New Hampshire.
