John McCain picked himself for vice president.
He picked someone whose life story is so heavy on the colorful that the media doesn't want to ask boring old policy questions; he picked someone people hesitate before criticizing because of that life story (ex-POW! working mom with Down syndrome baby!); and he picked someone who clearly spends an inordinate amount of time working that life story and courting that media love (not working crowds or climbing the political ladder swiftly, a la Obama).
In other words, he picked John McCain in a skirt.
