Could this be McCain's Miers moment? Some readers think so: the point at which people suddenly realize that McCain is actually less interested in governing than in politics. And willing to let personal liking and respect for utterly unqualified people trump the sober responsibilities of running a country at war, a climate in flux, an economy in trouble, and an empire close to imploding.

One more thing: this was a bit of a F-U pick, a personal, totally idiosyncratic, gut-level, aggressive piece of opportunism. Yes he can! And yes, it does underline his maverick, out-of-the-box brand. It makes me like his empathy for gutsy young women, even former beauty queens (is there footage of her contest out there?). But it also makes me less comfortable with the idea of him as commander in chief. It seems a less steady choice than Biden.
