It's a scam on their part.
The Fairness Doctrine gets passed, Beck, Limbaugh, Hannity, Boortz, Levin, et al have to give equal time to moonbats, or their stations do.
They take the money and run and start a RW talk show channel.
Libs take over the radio.
Advertisers pull out, people stop listening, ratings drop.
Obama claims talk radio is "too big to fail" and takes it over.
Voila. Propaganda machine.
