U.S. News blogger says Mike Huckabee is at the top of McCain's list.
UPDATE: Mike Huckabee blogs today about the Robert Novak column mentioned earlier. He disputes the notion that he's in league with anti-McCain evangelicals. (He is speaking in a few days at Patrick Henry College in Virginia, the Harvard of the Religious Right.) And he tells about being in the crowd for Carrie Underwood's show last night.
