primary voters often are forced to choose between their hearts and minds, ideals vs. electablility etc. with an eye on the other side's selection. deciding between who they would want to win in the fall versus who they think has the best chance to win in the GE.
the Huckaboom has served to remind DEM primary voters of the possibility of a GOP nominee from the religious right, which when combined with the words obama/hussein/muslim/madrassa etc. serve to give potential DEM primary voters a subliminal pause when they consider how obama's background could be used against him by such a GOP nominee.
and the ever-present possibility of another terrorist attack during the fall campaign must never be discounted.
Huckabee's ascendance in the polls has not translated into windfalls of money, as would be expected (especially with a tax-exempt base of supporters/networkers) Huckabee's early trickle of money has only doubled, or tripled at most.
the more one learns of Huckabee's history in Arkansas (the master tobacco settlement, the curious dimunition of other potential GOP rivals for the state spotlight, even the peculiar circumstances by which Huckabee gained the Governor's office initially), the more one could make a powerful case that Mike Huckabee's candidacy (and media-driven ascendancy) benefits the Clinton's.
the most curious question then becomes, "on purpose"?
