LONDONDERRY, N.H.-Republican presidential candidate Rick Perry might not be a betting man, but Newt Gingrich is.

Gingrich said today that he wants to make a bet with Mitt Romney after Romney went on "Fox and Friends" this morning and said Gingrich should give back the money he made as a consultant for bailed-out home mortgage corporation Freddie Mac.

"I love the way he and his consultants do those things. I would just say that if Governor Romney would like to give back all the money he's earned on bankrupting companies and laying off employees over his years if being, then I would be glad to then listen to him, and I'll bet you $10, not $10,000 that he won't take the offer," Gingrich said.

Romney on Saturday night offered to bet Perry was wrong at the ABC News debate when Perry suggested Romney left a line out of a reprint of his book, No Apologies concerning backing healthcare mandates. Romney said he would bet $10,000 that Perry's comments weren't true.

"He must have been really sure of himself," Gingrich said about Romney's bet. "I wouldn't bet that amount of money."

Gingrich said he was "startled" by the bet comment because he knows Perry very well. "I couldn't imagine he could cover a bet like that. He's been a public servant all his career," Gingrich said.

Perry said the Romney bet was "out of touch" and "pocket change for Mitt."

The most costly part of Gingrich's $10 bet for Romney today isn't the money, but the possibility that Gingrich is actually going to bat with the Romney campaign, retorting the negative ads being put out by the Romney campaign with catchy and digging lines against Romney. One example is in the ABC News debate when Gingrich said the only reason Romney wasn't a career politician is because he lost to Ted Kennedy in 1994.

Another possible costly situation for Romney is that Gingrich is gaining in the polls in New Hampshire and threatening Romney's former place as front runner across the nation. But Gingrich said today that the candidates are "all vulnerable everywhere."

"I think every voter is very worried about this country's future. Every voter is going to reserve the right to change their mind up until the last minute and anybody who thinks any lead is safe anywhere is very foolish," Gingrich said.

Gingrich will continue to campaign today, holding a debate with Jon Huntsman and a town hall later this evening Windham, N.H. before going back to Iowa Wednesday.
