If you find the Palin phenomenon fascinating, if alarmingly irrational, you will want to read the astounding rant on the subject from Matt Taibii, not published by Rolling Stone, but available via True/Slant. Here's a selection:
Palin’s paranoid ramblings and self-pitying tantrums on the way out of office not only didn’t injure her chances for national office, they actually appeared to help, as polls taken in the week after her resignation showed that 71% of Republicans were now prepared to vote for her for president in 2012. Just as she had during the campaign last fall, Palin defied rational analysis by making a primal connection with the subterranean resentments of white middle America, which is apparently so pissed off now at the rest of the planet for not coddling its hurt feelings in the multicultural age that it is willing to embrace any politician who validates its insane sense of fucked-overness.
Nobody understands this political reality quite like Palin, even if she doesn’t actually understand it in the sense of someone who thinks her way to a conclusion, but merely lives it, unconsciously, with the unerring instinct of a herd animal. Palin’s supporters don’t judge her according to her almost completely nonexistent qualifications for serious office, they perceive her as they would a character in a Biblical narrative, a Job in heels with cross-eyes and a mashed-potato-brained husband who happens to spend a lot of time getting shat upon by Letterman and Maureen Dowd and the other modern-day Enemies of Christ.
