I think that Mike Huckabee wants to be president, but doesn't want to run for president.
I'm actually not sure that he really wants to be president. Throughout the 2008 campaign, it seemed to me less like he wanted to be president, and more like he just wanted the other candidates and the media to take him seriously, and not treat him like a hick. He wants to be respected, and he wants his voters to be respected, more than he actually wants to be president, IMHO.
The 2008 GOP presidential nomination race was actually kind of weird, as it seemed like only McCain and Romney really wanted the presidency, while the others were just running to prove a point or something.
