None of the above. I think one of the governors would be a better choice: Daniels, Jindhal or Barbour.
Jindal would be eaten alive by the media with his exorcism stuff, and his Gilligan look. Unfortunately, Barbour is considered “too Southern” to be on a national ticket. Daniels, no one has ever heard of him, so if he’s interested, he better get busy.
Of the current crop, Palin has the best chance going up against 0bama. She’d be able to raise enough money to be competative, she’d be able to match him crowd for crowd, and have an army of get out the vote volunteers. None of the others are near as inspriring.
Jindal, as I recall, is not a NBC because his parents were not citizens when he was born here. Not that being a Natural Born Citizen means anything anymore - thanks SCOTUS.
