This was pretty much a Huckabee endorsement in this interview, I think he left his options open in case Huckabee doesn't run, but he made it clear that he has not waivered on Huckabee.
Question-Have you seen anybody who has given you inspiration?
DH: Well, as you know, last time I campaigned for Huckabee in 2008 after I got out of the race. I liked him because I think he understood the economic/security problem as it relates to our China policy. So I liked that. But its too early to make that determination.
You probably shouldn't think too much then. It seems rather problematic for you. It could have been worse. He could have mentioned Precious.
