What you fail to consider is that a leader manages. For example, he would arrange for a bunch of concrete trucks to show up on time, with the correct permits and licences, and dump the concrete where it is supposed to go. I doubt that he would be expected to know the engine displaced of the concrete trucks. Wisdom is not what a man knows but how he employs the knowledge he has. Only pedants think otherwise.
Trump didn’t arrange for any concrete trucks to show up anywhere. That was the responsibility of the Mob owned concrete companies he employed.
Trump has zero governing experience.
.
The only thing Trump understands about government is illicit pay-offs.
Who would he pay off?
Trump is lost in the woods. He has to fool more than twice as many people as he has so far.
Good luck on that!
