@Irishk,
I suspect that Huckabee (born Aug, 1955) will decide that he will take a hike until 2016 when he will be 61.
In recent years, candidates for President increasing tended to bubble up from state governors' offices as opposed to the Congress (particularly the Senate). I think I can prove that.
If true, the problem for Senators is that they will often vote strategically for or against some bill until an amendment is added or dropped. And that can come to haunt him/her when taken out of context by an opponent.
Now, in a relatively new development, we have the politician turned talk show host turned politician.
Does that make sense?
