Claire McCaskill: “It was time for this to end, and Joe Biden had the courage to do it.”

This is not Joe Biden. We have some of the least inflation in the developed world.

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.

There is an over-classification problem, and I was surprised Secretary Gates didn't mention it.

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.
