Having a modern American republican run a government is like having an old line communist run a large business. Contemporary Republicans do not believe in government, they think it is inherently evil and incapable of doing anything good or useful. Traditional communists do not believe in privately held profit driven corporations and think they are inherently evil and incapable of doing anything good or useful. A communist would run Proctor and Gamble into the ground in short order, and Republicans have proven they do the same for governments.
Republicans have short changed, handicapped and basically made a mess of government in my lifetime and then conveniently point at the problems government has and say "see, I told you it sucks". Why would anyone vote for them, esp. business people – republican are deal breakers, you can't do business with deal breakers!
