Not without some force acting on them. Positing Duncan Hunter as that influence is rather groundless IMO. If they're anything like normal people, they are not going to spend any time with each other, and if they do they will spend time together because they like and accept each other, "as-is, where-is," politics aside.
So again, Huckabee should veer right because...? There's no reason to. Right doesn't look like a winner today, and it has already taken Huckabee as far as he's going to get.
Alright, my first answer was a good one, but since you asked for a second answer . . . Mike Huckabee might just veer right because not all men are as cynical as you are.
I do know enough about Duncan Hunter’s background, affiliations and faith to believe that it is VERY possible that the two men are having very regular communications on several levels.
