I am not 100% decided yet but I am leaning towards Nathan Deal.
I have a couple of problems with Deal. Congressmen do not historically make good chief executives. Deal was a democrat who jumped ship when the republicans took the house in 1995. He has been in Washington 17 years which to my mind makes pretty much anyone unfit for anything. He is also fleeing ethics investigations related to a company he is partners in that received some lucrative no-bid contracts from the state.
I am down to Chapman or Johnson by the process of elimination.
