Perry says $10,000 is like 'pocket change' for Romney

"The idea that I would have $10,000 to make a bet is a little out of the ordinary," said Perry on the campaign trail.

In a heated exchange during Saturday's GOP debate, Romney offered the bet in defense against Perry's claim that he was hiding past support for individual healthcare mandates.

Opponents have seized on the debate wager, hoping to paint Romney as out of touch with voters faced with economic woes. 

"I was thinking about it this morning … and all those houses that I was driving by, probably most of them that we fly over this afternoon, that, that is way out of the ordinary for most Iowans," said Perry to reporters.

"I would suggest to you that $10,000 is pocket change for Mitt to make that statement, but you'll need to ask him, maybe it was just a misstatement," he added.

Romney defended himself Monday, saying his bet to Perry was “an outrageous number to answer an outrageous charge from Rick” in an interview from Manchester, N.H., with "Fox and Friends."

“It’s like saying, 'hey, I’ll bet you a million bucks X, Y and Z,' ” said Romney downplaying the bet.

He added that his wife had also teased him about the exchange. Romney said that after the debate she had said, “ 'Hey Mitt, it was a great debate and you’re great at a lot of things, just not betting.' ”
