Gingrich brushes off fears his campaign could 'implode'

Current GOP presidential front-runner Newt Gingrich on Wednesday dismissed concerns from his critics that his campaign could collapse after a misstep or gaffe.

In an interview on CNN, Gingrich was asked by Wolf Blitzer if he was concerned about making a blunder that could end his campaign.

"Your critics say you, Newt Gingrich, are fully capable of imploding, if you will. Making a mistake, a blunder that could turn things around. Are you worried about that?" asked Blitzer.

“Sure. It would be a bad thing. Is it possible? I guess,” Gingrich replied.

But the former House Speaker added that his long record of public service would help him rebound from any controversy.

"On the other hand, I've had a very long career and I have a very public record and I think people are coming to decide that they like substance and they like somebody who has actually balanced the budget, reformed welfare, cut taxes — gotten it done for real," he said. 

"I think there's probably a little more resilience in my support than in some of the other folks that have made a run at this," added Gingrich.

Gingrich, who has jumped to front-runner status in GOP polls, has faced criticism from rivals for many controversial statements. Most recently he came under fire for comments suggesting that poor children lacked a strong work ethic.
