Huckabee is likely only in it to siphon off votes so that Jeb Bush can get the nomination.
That is a well-worn tactic from Rove’s bag of tricks. Thing is though, I’m getting sick of “freedom loving” my-way-or-the-highway atheists telling us what we can and cannot do and think. Christian candidates do get consistently torpedoed by their own side, and somebody is scared poo-less by Cruz. Thing is that I’m not sure what Cruz is actually good for. Bush family members do need to be avoided at all costs if for no better reason than an overly sentimental take on “friendship” the taxpayers get stuck footing the bill for and the tendency to kill off everything but the most groveling of yes men.
