Ross Douthat tries to defend Sarah Palin:

Most of the attention has focused, justly, on Palin's flat-out incoherent answers to some of Couric's questions, and her difficulties deflecting obvious "gotcha" situations (Gibson on the Bush Doctrine, Couric asking what newspapers she reads and asking her to name non-Roe Supreme Court decisions with which she disagrees, etc.)

Those may not seem like "gotcha" questions to you, but the difficulty they pose is immense, as they require Palin to evaluate Supreme Court decisions, or published commentary, taken as a whole.

If, instead, she'd been asked about, say, the votes of individual Supreme Court justices, or some particular article in Foreign Affairs, there would have been no difficulty whatever.

Right?
