I think that there are many things we can get mad at Trump for, but simple vocabulary isn’t one of those things.

Trump is still not understandable even given the simple vocabulary, which is a huge strike against him.

You said it all, the two paragraphs in between are true, but not really relevant to the situation.

Trump isn’t speaking simply because he is brilliant educator, it is because he is dumb - which is not good qualification for the president.
