Agreed 100%. But let's remember that Rush likes to emphasize how he never listens to other talk show hosts. So unless he gets A TON of critical emails from his audience, he simply may not know how Mark performs or what Mark is saying.
(Not at all good. But then nobody is perfect, not even Rush!)
Rush has always followed the same thinking, at least until recently. I have never heard Rush seriously put principles above party. Not that I have listened to him much in the last couple of years. Maybe he has changed his tune. I know he detested McCain. Maybe that turned him around.
