I would ask him to list the so-called weaknesses of evolution that he felt needed to be protected and promoted by law, because there are none. (Brush up on "Irreducible Complexity", and do not accept it as an answer as it has been thoroughly debunked.) Why did he open his state up to a lawsuit to promote a stealth-creationist agenda? Since he's Catholic, is he aware that the Vatican accepts evolution and has rejected Intelligent Design? And what about that exorcism he took part in?
