re: He did
There are plenty of contradictions on both the conservative and liberal sides. There is also plenty of prejudice on both sides.
I personally do not like to see amendments to the Constitution unless its something really import. The marriage thing Huckabee wants to amend is not something that need to be amend. But the Human Life amendment could be important enough, but I need to see the details of it.
Anyway, you don't need to worry. There is no way Huckabee will be nominated or elected. Too many people are scared of his religious background.
