Not as significant as the NRO item, but here's Ann Althouse, via an instapundit link:

Sorry, but I thought Palin's response Couric was painfully awkward. (I really don't care about Couric's problems.) Palin had a substantial knowledge gap, and she didn't know how to hide it. It felt too much like the possibly forgivable "In what respect, Charlie?" And when combined with the news that the campaign seemed to be finagling to move the VP debate to a later time, it made her look they way her opponents have been trying to paint her: unprepared and weak. It's really not good enough.

And here's Rod "Crunchy Con" Dreher admitting he was wrong about Palin:

I remember the morning I woke up in my college dorm room and went in to take my final exam in my Formal Logic class. I knew I was unready. Massively unready. And now I was going to be put to the ultimate test. I sat down in Dr. Sarkar's class and resolved to wing it. Of course I failed the exam and failed the class, because I had no idea what I was talking about. I wasn't a bad kid, or even a stupid kid. I was just badly unprepared, and in way over my head. Seeing the Palin interview on CBS, I thought of myself in Dr. Sarkar's exam. But see, I was a college undergraduate who had the chance to take the class again, which I did, and passed (barely). I wasn't running for vice president of the United States.

It's like a talking points machine gone out of control. Or magnetic poetry that you have on your fridge—in fact, you can try it at home. String together key words and phrases like "shore up the economy," "reduce tax rates," "healthcare reform," and "trade" and see what kind of Palinisms you can create.

I would like to imagine that the devoted fans of Sarah Palin, the people who believed her to be Reagan and Joan of Arc combined, who held out such hope for her as a future leader in the GOP and conservative movement, will be as irrationally and powerfully angry at McCain for putting her in the impossible position she is now in as they were enthusiastic about the selection of her in the first place.

And now, an excerpt from my inner monologue, as transcribed while watching various clips from Sarah Palin's interview with Katie Couric (I can't link to them; they're too painful):  And that, Douthat, is why nobody's ever going to hire you to help pick their running mate.

(with links to his former support of Palin for veep).

Heckuva job there, McCain.
