“The problem for Newt is, this is exactly what everybody who has ever worked for or around him said was his basic problem,” said Rich Galen, the veteran Republican strategist and former Gingrich aide. “Sooner or later, I suspect, unfortunately, the campaign will collapse from the top because people are going to say, ‘I love him and he’s really smart, but he can’t be president.’”…

The candidate himself sounded a defiant note on Fox Tuesday night, largely blaming the media for his woes and vowing not to participate in any more “gotcha games.” Gingrich also refused to answer a question about a POLITICO report that he and his wife, Callista, amassed up to $500,000 in debt at Tiffany’s.

“If it doesn’t relate to solving our problems, from now on my answer’s going to be, ‘I’m not commenting on it,’” Gingrich said. “I’m not playing Trivial Pursuit.”
