This was more of Herman being Herman. I saw Face the Nation and my take was he was backtracking.
Notice he met with Sheriff Joe and Joe is now backing Perry. He must have not been able to completely convince Joe he was serious or knew what he was talking about.
I agree, but he did that on so many things. Say something one day, say he was kidding the next and reiterate it the third day........ Not a good thing for a Politician.
