It is a bit unnerving to see Limbaugh, of all people, conflating Power and influence.
Rush is a smart guy and I suspect somewhat of a binary thinker like me. He understands that “the right thing to do” is not always the right thing to do. It can cross the line into being a wrong thing. I think his point is that Under some circumstances, Trump SHOULD say what he is saying, but under others, it is really inappropriate for the “office of the president” to go there. And the difference between the two situations can be almost undetectable by most people.
