Mitt Romney says he's in the presidential race to the bitter end -- win or lose in the early primaries.

"We're going all the way through Feb. 5 - no ifs, ands, or buts about it," he said on CBS's "Face the Nation." "This is a race that is not going to be decided by a few states. It's a race that I'm taking to the nation."

Meanwhile, New Mexico Gov. Richardson, who at least understands Western issues and made several trips to Utah over the last year, has dropped out of Democratic race. A Latino with foreign policy experience, Richardson could wind up an interesting addition to a Democratic presidential ticket.
