Mike Huckabee clearly rubs some members of the republican coalition the wrong way. Socially conservative evangelicals like him. Immigration hawks seem to loathe him. Tax crusaders are suspicious of his record in Arkansas. But in both these cases he seems to be making gestures in the direction of his critics.
But life in the Republican Party is complicated. Some business Republicans (who have allies on the editorial board of the WSJ) are "wet" on immigration. Some evangelicals are not. Most Republicans favor lower taxes, albeit for somewhat different reasons. The question is whether the lower taxes/less government foundation is sufficiently sturdy for a new house. And how many rooms will the new Republican mansion have?
