I very much think Trump is the exact same way. He knows a lot of business and his business, but he knows absolutely nothing about governance. That's not necessarily because he's a bad person, but because he's an extrovert and the type of extrovert who learns from experience and not from books. Evidence of the this is the violence at his rallies, when is the last time that happened to a Presidential candidate? I think the sort of policies he's going to push are going to lead to a lot of problems in the world for America in the long run. But it's very likely that he will be elected.

Also in terms of intelligence, getting a lot of money early in life and then making lots of small time investments in a lot of companies and having them turn into unicorns is not necessarily signs that you are super intelligent. You can just as likely just be lucky, and it be a case of survivor-ship bias.
