Almost half of Republicans say that Mike Huckabee should continue his campaign despite John McCain’s seemingly insurmountable lead, according to Gallup. The Feb. 21-24 survey found 49 percent said he should continue and 46 percent said he should drop out. Predictably, conservatives want Huckabee to keep running by a 54 percent to 42 percent margin compared to moderates who say 57 percent to 38 percent that he should withdraw.
