Steyn never gets time for show prep, and is not by nature a radio guy.
He does remarkably well for a fellow that just gets the 3 AM call up.
Rush is the consummate radio professional.
He has time for show prep, he knows how to use the pregnant pause when speaking.
He is serious yet humorous.
He can relate to the little guy and the guy in the penthouse.
Most of the time Mark Steyn knows he has an upcoming job subbing for Rush. He has plenty of time for show prep. Yes, I am aware of a few times where he got a last minute call to sub for Rush but this is the exception. When Steyn gets really revved up he's like Alvin and the Chipmunks on helium
