Newt Gingrich starts to surge and lands in the top 3 in several polls.
Another Republican candidate makes an embarrassing slip-up. This time it's Herman Cain.
Asked if he supports President Obama's policy on Libya, Cain didn't seem to know what it is.
Cain brushed off criticism of his response. Aides say he had just four hours of sleep before the interview.
The Milwaukee Journal-Sentinel asked Presidential candidate Herman Cain if he supports President Obama's policy on Libya. "I don't not agree with him for the following reason. . . Nope, that's a different one. . . I gotta go back and see got all this stuff twirling around in my head," said Herman Cain (R) Presidential Candidate.
Cain even seemed to ask the reporter for help, "President Obama supported the uprising, correct?"
Eventually, he gave an answer, then later explained, "They asked me a question about Libya and I paused so I could gather my thoughts," said Cain.
But can that kind of halting response, just days after a major foreign policy debate, survive a presidential campaign? "When people start feeling sorry for you watching the video, that's when you know they're not going to vote for you," said E.J. Dionne, Jr. of Washington Post.
But might they vote for Rick Perry, whose poll numbers sank after his own embarrassing brain fade last week? "I'm not the most polished candidate out there, but let me tell you one thing I stick to my principles," said Rick Perry (R), Presidential Candidate.
Newt Gingrich is most benefiting from all of the memory lapses. He soared five points in a week, now in the top three in two major polls.
If all this pushes Mitt Romney to the nomination, that could be good news for President Obama. The latest Politico poll has him beating Romney by six points.
