Allahpundit thinks this is going to destroy him, but I'm not so sure. First of all, conservatives have shown themselves to be very forgiving about ignorant responses to foreign policy questions and Cain has had several already. Secondly, most Republicans are focusing on the economy which makes it far more likely that Cain's "9-9-9" plan - falling apart the more scrutiny it receives - will be his undoing. New Hampshire, for instance, has no sales tax presently and Cain's 9% sales tax would vastly increase the tax burden for NH residents alone.
Allah has some sharp analysis of Cain's foot in mouth problem:
When I hear him give answers like the one he gives below about Gitmo, it makes me wonder why he wants to be president in the first place. If you're this disengaged from one of the executive's core duties, why would you want those duties at all? It'd be like me trying to get hired at an accounting firm because I think I can "make a difference" even though I know zip zero zilch about accounting. Normally I hate pop-quiz foreign policy questions that candidates get like "Who's the prime minister of Nigeria?", but after all these gaffes I'm thinking the media's well within its rights at this point to test Cain on basic stuff. And I don't mean who the president of Ubeki-beki-beki-beki-stan-stan is. I mean stuff like, "Is Iran a Sunni or Shiite country, and why does that matter?" Anyone who's read the news intermittently over the past 10 years should be able to offer a basic answer to that one. I'd be curious to hear Cain's.
This plays into AT political correspondent Rich Baehr's suggestion that Cain had no real expectation that he would ever be a contender and is surprised to be where he is. He's trying to play catch up but the gaps in his knowledge are being exposed and it's not very flattering.
Oh - and if he answers one more time that he "misspoke", or that he was "joking" when he makes some verbal flub, he will only make himself appear even less sure of himself, and less qualified to play with the big boys.
