The attack on Obama was very deft. Palin went right for Obama's fundamental weakness--that he's never done anything impressive. (And by giving such a good speech, she partly undermined his claim to be the only one who could speak impressively.) For example, consider this line--which I predict will be remembered two months from now: "I guess a small-town mayor is sort of like a 'community organizer,' except that you have actual responsibilities." This deflates all the sanctimonious praise of Obama at the Democratic convention for all his selfless years as a community organizer. And if you take away the community organizing, Obama's just a career politician, one "who has authored two memoirs but not a single major law or reform," one of those who has used "change to promote their careers." What's left of Obama's résumé, and his claim to deserve the presidency? Not much.
