As much as I love Donald Trump, and welcome all his efforts to make America Great Again (and he did), he is not the best speaker he can be. He uses too many of the same euphemisms and patterns of speech, and too often makes assumptions that those he is speaking to know what he is talking about.
Rush himself has said this.
Could Donald Trump do it 3 hours a day 5 days a week? YES. He is indefatigable. But he needs to learn how to do radio. It is an art.
I think Trump has bigger and better ideas in mind.
