Gingrich vows to fight on

Despite winning just one state last night, Newt Gingrich is vowing to stay in the race.

"We are staying in this race, because I believe it is going to be impossible for a moderate to win the general election," Gingrich said.

He dismissed Rick Santorum as a "good team member," but one who can't change the game.

"With all respect to my friend from Pennsylvania, Sen. Santorum," Gingrich said, "there is a big difference between being a good team member and changing the game."

The comments are similar to what Gingrich said this morning on Bill Bennett's "Morning in America" radio show.

"If I thought he was a slam dunk to beat Romney and to beat Obama, I would really consider getting out," Gingrich said of Santorum on the show. "I don’t ... I think each of the three candidates has strengths and weaknesses and that this is a very healthy vetting process.”

Gingrich refused to set the bar of when he might drop out.

"If you asked Rick Santorum that question immediately after Nevada, what would we have said?" Gingrich retorted. "He had been running fourth for a month and -- including me -- people were saying maybe he should drop out. He ignored all those. He now has had a terrific month. I think you have to wait and see how the race goes on.”
