Sarah bluffs her way through a foreign policy question on "the Bush doctrine".  She doesn’t know what it means, even after he gives her a hint.

I’m not sure what makes her a unique politician.  She’s slick! the way she bluffs through that.

Of course, there’s a reason she doesn’t know what he’s talking about.  This is Sarah in December 2006:

"I’ve been so focused on state government, I haven’t really focused much on the war in Iraq."

** UPDATE **  In a piece too long and perfect to truncate, James Fallows explains why Palin’s non-recognition of the Bush Doctrine matters.

She also took the position (somewhat craftily) of A-okaying an unnnnounced strike against terrorists in Pakistan.  Unfortunately, that’s not the same position as McCain — it’s Obama’s position, and McCain has been attacking Obama about that.

Ooops.

Publius sums it up nicely:

You could almost hear her mental gears grinding, trying to retrieve the talking points and forcing them into her answers. Nothing came from her — or if it did, she certainly fooled me. Reagan and Clinton — governors both — would never have appeared that ignorant, largely because they weren’t. They were engaged with the issues of their day and wrestled with them intellectually. Today’s interview reflected an unprepared, uninformed person cast into the spotlight far before her time.
