What is he skilled at?
First you never end a sentence with a preposition and you just did. So..he is skilled at grammar.
Second you obviously don’t listen to the man at all otherwise you would know his skills.
He knows his history
He knows his politics
He has one helluva business sense
He is a professional
Tell ya what? Why don’t you have your people call his people and set up a debate and you could pick all the topics. All Rush has to do is show up. THEN you would find out firsthand what Rush’s skills are.
Now you owe me an apology.
