Steele vs. Limbaugh?

I don't fully understand this supposed feud between Rush Limbaugh and RNC Chairman Michael Steele. Steele is the leader of the party. Steele apparently said that "Rush Limbaugh is an entertainer". As far as I can tell that is a true statement. He said that Limbaugh can be "incendiary". I think that is true too. He might have gone a little too far when he said that the show can get "ugly", but in I don't think it is that far out of line and as leader of the party, I think he has to have some space between himself and bomb-throwers such as Limbaugh. Limbaugh went off on Steele on his show today and I thought Limbaugh was out of line. I think his CPAC appearance must have gone to his head. BTW, good article on "the feud" here.
