Huckabee lays out a possible path to the nomination here on Special Report-
If I had to bet, I'd say Mike Huckabee will not be the Republican nominee in 2016. Outside of Iowa, and maybe South Carolina, what states can he win? The evangelical vote will only get him so far and it will be much tougher for him this time around. Not only will Rick Santorum be competing for those votes, but Senator Ted Cruz and Governor Scott Walker, both of them are the son of a Pastor.
Also, Huckabee left the Governor's office in January of 2007, over 8 years ago. I don't see Huckabee's path to the nomination.
Laura Ingraham agrees: The idea that Mike Huckabee is going to be President of the United States? That's not going to happen
"I like Mike (Huckabee) a lot, I think he’s really strong. But he would probably do better serving conservatism if he had run for one of the two open Senate seats in Arkansas over the last several years. He decided not to do that, and had a great show on Fox. But the idea that Mike Huckabee is going to be President of the United States? I’ll predict that that’s not going to happen”
