Like prominent Republicans from, well, Mississippi (Gov. Haley Barbour) to Alaska (c'mon you can do it), Mike Huckabee admits that he mulls every day whether he should enter the wide-open GOP presidential contest.

But unlike other Republican White House dreamers -- with the conspicuous exception of the indefatigable Mitt Romney -- Huckabee knows the adrenaline rush and the arduous pressures of a presidential race from his quest for the 2008 GOP nomination. "If you've jumped out of an airplane," Huckabee told Washington political reporters Wednesday afternoon, "you have a whole lot better understanding of what you're going to do the next time you do it because you've done it."
