Trump fairly certainly has a very high IQ - I do have one well above the average, and I can see the signs when he talks - but the problem with that is that it makes it harder for you to get people with normal ones. He seems to be fairly astute when it comes to communicating with normal people, but that is probably because he has deliberately learned to do so. High IQs don't mean you can do or understand everything with no effort, it just means that you can see connections and patterns more easily and can get stuff a bit faster when you do study it, it pretty much seems to have to do with something like processing speed. But you still need to study and learn it, and when it comes to dealing with people with normal IQs you can still slip from time to time and say or do something they can't get the way you meant it.

Think about it. The average IQ is 100. Think about trying to communicate or explain something to a person whose IQ is something like 80 or 70. Then consider the fact that the gab is equally big when it comes to somebody with an IQ of 130 communicating with somebody with that 100 IQ.
