Even Rush knows you can't build a house on sand. Conservatism is the rock hard foundation upon which the success of this nation (and Rush) is built.
If most people are like me, they listen almost exclusively to the radio at work, driving to and from work or driving between jobs.
Lieberals, on the other hand, collect a government check and turn on the TV. So the difference in audience demographics is a key factor.
Michael Savage has stated on air repeately that he has equal time lawyers on retainer and ready to move against MSNBCBS and the rest of the enemedia to demand equal time if the fairness doctrine is ever reimposed.
Rush and the rest should do the same. It would give every Lieberal nazi pause that they might have to open their broadcast monopoly to other ideas as a consequence of trying to shut down conservative talk radio.
