On balance, she's probably an asset to John McCain. But we should stop pretending that she is ready now or anytime in the forseeable future to be Commander-in-Chief.
I reached this conclusion after watching the foreign-policy portion of her disastrous Sept. 25 interview with Katie Couric. A number of commentators, including The Atlantic's James Fallows and Slate's Christopher Beam, have said that Palin resembled, in Beam's words, "a high-schooler trying to BS her way through a book report," which is an insult to both high-schoolers and B.S. Palin's answers were hesitant, convoluted and at times — like when she appeared to suggest that Vladimir Putin might be preparing a one-man airborne invasion of Alaska — downright loony.
But the more worrisome responses were the ones that betrayed her lack of curiosity about current events and reliance on bumper-sticker wisdom over complex thoughts. There were moments, in fact, in which you wondered whether she had been paying any meaningful attention to the world outside Alaska before McCain picked her as his running mate a month ago.
