I'd feel sorry for Palin, but she asked for it
Should a vice-presidential nominee be expected to know what the Bush Doctrine is? Here is Sarah Palin at that cringe-making moment when she is asked a question she doesn't understand. Luckily, the friendly host Charlie Gibson lets her off the hook.
The whole thing reminds me of my French oral exam: no matter what the question, I simply worked back to my memorised stock phrases. Doesn't mean I could speak French though.
I don't know if she's even aware yet that there are such things as vice-presidential debates.
Good luck against Joe Biden.
