Gingrich: Race will come down to 'Newt and Not-Newt'

Former House Speaker Newt Gingrich said the tables have turned in the Republican race for the White House, arguing on Wednesday that he's replacing Mitt Romney as the GOP's most steady presidential front-runner.

"I would have thought originally it was going to be a 'Mitt and Not-Mitt'," Gingrich said, talking about his early predictions for the top two Republican contenders. "It may turn out to be 'Newt and Not-Newt,' and that's a very different formula."

Gingrich has seen his poll numbers spike in the last month, taking him from the single digits into the top tier and in a close match with the former Massachusetts governor for the top spot.
