Claire McCaskill: “I want to know, generally speaking, the vig on a bookie bet. You are the house. You are the bookie.”

He's focused on himself?

I think that, fundamentally, voters do understand that we have very, very low unemployment. They see it in their families, that everybody has jobs, everybody can get jobs, their jobs are paying slightly better.

I have won when the polls said I couldn't and I have lost when the polls said I would win, so I am not a big believer in all of the horse race stuff.

This is never a referendum. Presidential elections, by the time they run around, is always, 'well, who do you like slightly better than the two you don't like?' So it is a binary choice.
