I'm actually sitting in Barry Goldwater Airport in Phoenix, Arizona, and it's really fun to be writing about John McCain from his own home turf. Or the turf that some of his homes rest on, apparently. This morning, John McCain announced the choice of his running mate, Governor Sarah Palin of Alaska. Trapper John calls the choice Worse Than Quayle. The New York Times says Old Man John is "shaking up the political world at a time when his campaign has been trying to attract women." What's truly remarkable here is just how much Hillary Clinton continues to form the political dialogue of the Presidential race. From the lavish praise heaped on her in Obama's aceptance speech yesterday to now providing the obvious rationale for John McCain's selection of a potential chief executive - Booman notes John McCain's age and health issues, impolite, but necessary - Hillary Clinton is still driving the narrative of this campaign.
