Why won't Limbaugh interview with Bill Maher?

FOX is a news network. They are (I ume) pretty near to the size of the other big networks. Would it not be logical to ume they are all the same? With big companies, they either emulate each other, or the little one gets tossed out. If FOX was conservative, or even balanced, the other networks would run them out of business. FOX is not balanced, because no one is.
