The GOP was invaded/taken over by the libertarians. The libertarians (the Ayn Rand fan boy types, not your average liberty loving person) are a small portion of the electorate, the Christians are a huge portion of the electorate. They want your votes, not your input.
Huckabee is likely only in it to siphon off votes so that Jeb Bush can get the nomination.
I don’t think it’s the Ayn Randian libertarians that are the problem,
but the actual Big Government Republicans.
Neither care for Christian input.
