I cetainly wouldn't tune in to Limbaugh - if he apologises it would only be because he was directed to and, having seen what he has already been capable of was enough to turn my stomach. Why would I want to see more?

The only reason I might tune in would be to take a note of the advertisers during the breaks and to write them letters stating that I, for one, would not use their products if they were associating themselves with this piece of filth. Wouldn't make much impact unless a lot of people did it, but could be fun!
