Well, for starters, he gave us Obama (just taking a swipe at the ‘Bush gave us Obama’ folks).
Huckabee had nothing to do with Obama, Romney did that by sending out the message early not to even think of entering the 2008 primary, because he had the establishment support, and the organization, the manpower, the big donors, and all his personal wealth already lined up.
Romney kept out the big dogs, and still lost to McCain and Huckabee.
