“...Limbaugh’s potential audience is larger than that of liberal competitors because more liberals say they will listen to conservatives than vice versa.”
Ah...so the message of this article is that Libs are more open minded than us narrowly focused bigots of Conservative persuasion. I say BS. If Libs are listening to Rush, then it is solely for the purpose of nitpicking his philosophies, and trying to find error or misstatements to ram him with.
Being extremely hard of hearing, I find the program difficult to attend due the excessive advertising (for me, very tiring). I enjoy reading at his site though. Rush has quite a great mind.
If you subscribe to Rush 24/7 you can get delayed podcasts in the form of 3 mp3 files, each with one "hour" of programming, which is actually considerably shorter than that because it omits the commercials and the newscasts entirely. Costs $50 annually.
