To me personally? Nothing. If it translates into him getting the GOP nomination, Obama will be the happiest person in the room.
The country is not going to vote for an arrogant college professor. (Who also happens to be a cranky old geezer with a hell of a lot of baggage.)
And Iowa, I might add, is not likely to ignore the baggage. They are a family values kind of state.
Pay closewr attention ... Newt is polling very high in Iowa and tonight the Iowans appeared to really like listening to him.
