No, not really. I have thought (often) that no conservative can win without the support of the evangelical base. And I do think that good ol' socon evangelical values alone will not do the trick, but I don't think Huck or Cruz or any evangelical would run on such a narrow platform. Cruz, for sure is right on those values but also economic and political positions also.
The last one to subsist only on his evangelical base was old Pat Robertson. Do you remember that? A disaster.
Actually I was thinking about Michele Bachman and her like minded types and others. She was a very competent congressman with years of battle scars. These do not win the nomination.
Cruz is a genius, but he is stuck I presume by wanting to be able to function in the future as a senator, and can not be the force as Donald Trump can be with that kind of freedom to cast stones and actually land them.
