Sarah Palin is eerily similar to the Obama of the right. Yes, she is a less intelligent version but the stuff we've heard from the McCain staff is far from believable. Palin can draw huge, passionate crowds (and, since a string of embarassments, the energy has been positive) and we have all seen what this ability can be parleyed into. I'm not saying that she's as smart as Obama but she is as charismatic and just as good a politician. There is nobody else in the Republican party that can draw the kind of crowds that Palin can.
She didn't Quayle or Edwards her debate. She has four years to make up for the Couric interview and the shopping spree. And, sometime before '12, she'll have a successful book ghostwritten for her.
