Good point! Rush has a tremendous following and he has never pretended to be 'fair and balanced.'
You're right. Rush gets around 20 million listeners a day. If Fox or any of these cable channels held an audience of 1 million--or even half a million--for an hour they would throw a party.
If Rush has 22 million listeners (and I do not know if that means in a 3 hour period or in a week), can you imagine what type of viewership a cable news channel would get if it went totally and unabashedly conservative. It would be on in my house constantly.
