PRO: Of all the 2008 Republican contenders, the guitar-playing, carb-hating former governor of Arkansas remains one of the most visible, landing a talk show on Fox News and pushing a best-selling book.
CON: If the GOP's identity struggle produces a more centrist platform, Huckabee's anti-abortion, pro-evolution stance could be problematic.
