Says it all.
By the way, Christopher Hitchens nails Sarah Palin Bible Spice in Newsweek. An excerpt:
The Palin problem, then, might be that she cynically incites a crowd that she has no real intention of pleasing. If she were ever to get herself to the nation's capital, the teabaggers would be just as much on the outside as they are now, and would simply have been the instruments that helped get her elected. In my own not-all-that-humble opinion, duping the hicks is a degree or two worse than condescending to them. It's also much more dangerous, because it meanwhile involves giving a sort of respectability to ideas that were discredited when William Jennings Bryan was last on the stump. The Weekly Standard (itself not exactly a prairie-based publication) might want to think twice before flirting with popular delusions and resentments that are as impossible to satisfy as the demand for a silver standard or a ban on the teaching of Darwin, and are for that very reason hard to tamp down. Many of Palin's admirers seem to expect that, on receipt of the Republican Party nomination, she would immediately embark on a crusade against Wall Street and the banks. This notion is stupid to much the same degree that it is irresponsible.
Then there's the question of character and personality. Decades ago, Walter Dean Burnham pointed out that right-wing populists tended to fail because they projected anger and therefore also attracted it. (He was one of the few on the left to predict that the genial Ronald Reagan would win for this very reason.) Let's admit that Sarah Palin is more attractive—some might even want to say more appealing—than much of her enraged core constituency. But then all we are considering is a point of packaging and marketing, where charm is supposed to make up for what education and experience have failed thus far to supply. We are further obliged to consider the question: exactly how charming is the Joan of Arc of the New Right, who also hears voices speaking to her of "spiritual warfare"?
He also writes: "Sarah Palin appears to have no testable core conviction except the belief (which none of her defenders denies that she holds, or at least has held and not yet repudiated) that the end of days and the Second Coming will occur in her lifetime."
