Former Arkansas governor Mike Huckabee
Shied away from the "demolition derby" conflict of the leading candidates and embraced his conservative faith in his signature (ever popular) style. Explicitly put aside humor to say, "There's nothing funny about Hillary being president," and darn near came off as presidential. But never challenged (or was challenged by) any of the four guys ahead of him, which is still necessary if he's going to have a chance.
