If any other Governor from any of the other 49 states suddenly arrived on the national scene as a complete unknown to all except a very small handful of people, then they too would face the scrutiny that Palin has received. In fact, probably even more so.
Thus far, all I know of Palin is that she was mayor and a city council person in a city with a population under 9,000; that she has been governor of a state with a small population for under two years; that most of her biography of her short political career has been either embellished or (worse) fabricated (e.g. she actually supported the bridge to nowhere; she supported ear marks; etc.); her husband used to be a member of a secessionist party and she addressed that party this year; she recently addressed a bizarre church that believes that Alaska is the only place that will be safe from the coming apocalypse; she is currently under investigation; and several weeks ago she admitted that she didn't know what the VP did.
So, yeah, I want the media to do much more in vetting this woman than the McCain camp did. Sorry, that one speech is not enough for me.
