Why do you say that?
I see him as having not much of a chance to win. His personal polling data would have to show him this. I think he is not thinking of the bigger picture (too stubborn) which is to stop liberal Romney. He blew it long ago when he governed as a liberal republican. He would gain more respect by supporting one of the others. Apparently, he wants to go down in flames with some ridicule. What else is there to say.
