Your post doesn’t make a lot of sense. McCain and Romney both made professions of their faith, and both have told demonstrable lies.
Who did Duncan endorse?
I have yet to see the “demostrable lies” told by Romny (except as characterized by Huckabee).
As for Hunters endorsement, I’m dumbfounded by it. It probably had to do with the Minuteman endorsement, which I heard, has since been recinded.
