The U.S. presidency has become a committee of a couple of dozen well connected and well educated people who advise a single, charismatic, photogenic person who implements the policies decided by the committee.
This may be objectionable, especially to those who have never considered the idea and who are accustomed to hero-worship. But it is unreasonable anymore to expect a single individual to have the capacity to handle the duties of the office. No single person knows the intricacies of energy and science policy and is at the same time able to negotiate trade or arms agreements with a variety of nations.
But that's just want most Americans want and expect from their president. They want John Wayne (as Gil Scott-Heron once surmised) or George Washington. A man who will walk over and punch the collective Islamic State right in the nose and tell them to sit down and shut up. Then walk calmly back home. That's an allegorical scenario but that kind of thing is just what this country thinks it can find if it just keeps looking for the right candidate. Delusional is what I would call it.
