If your idea of a good gov. is someone who is unaffiliated with a political party, owes nothing to big business or lobbyists, has a sense of humour, was a champion chess player at 7, has a BA in psychology (honors), served in the Peace Corps and founded an animal rescue ranch then I'd say he'll be a great Governor.
I think people underestimate what it takes to have a successful career as a musician and author. He has a proven track record as someone with intelligence and dedication and his openness is legend, what more could we ask for in a public official?
