Why was Ben Carson not smart enough to understand what vetting is?

That is a damn good point. Hell, Bush was (*)(*)(*)(*)ing retarded, and was obviously unfit for office.

Oh, and the reason why not many of Carson's patients support him is because a good number of them hate him. He was sued by a good number of patients.

He was not that good of a doctor. The surgery that made him famous, the first "successful" separation of conjoined twins, was not that successful, The first twin died, and the second had brain damage, and other doctors who reviewed it said the damage could have been avoided.

Doctors who worked for him hated him, mainly because he blamed his mistakes on them. The girl he deformed was deformed because he neglected to review her chart and missed several complications that other doctors had discovered. He claimed he was never given her chart, a lie, and blamed it on his staff. Other doctors called him out on this, saying that any doctor who would perform a surgery without reviewing the patients information should have their licensed revoked, and that if he were telling the truth, and that he was not given the girls chart, he should have requested it, instead of simply going in blind.

 

The Governors alone are a case for voting Republican this cycle. Kasich especially is about as moderate as you'll get. Yes, he's keen on fiscal responsibility (what a concept ) but otherwise he has all the background, experience and temperament anyone should want from a POTUS. And unlike Hillary who declared she's proud to have Republicans as enemies, Kasich has a track record of working successfully across the isle. If you doubt the importance of this, look at what happened when Obama tried to lead in isolation; a complete governance failure.

You're still downplaying the skills needed to reach the highest level of business. Most career politicians would melt in that environment. As far as CEOs getting fired, it happens far more than you're acknowledging:

If you were a CEO in 2012, you had a 29.4% chance of being axed. That's hardly insignificant.
