Charles Krauthammer on Fox the other day drove that point home by completely dismissing her as a potential candidate:
Krauthammer: Now, as to Palin, I agree entirely with what Mara [Liasson] said -- she is, she has star power without any doubt, she has an extremely devoted following, but she is not a serious candidate for the presidency.
She had to go home and study and spend a lot of the time on issues with which she was not adept last year. And she hasn't.
She has to stop speaking in cliches and platitudes. It won't work. It could work for eight weeks if you're the No. 2 candidate, as she was last year. But even so, she got singed a lot in that campaign. You cannot sustain a campaign of platitudes and clichés over a year and a half if you’re running for the presidency.
