Trust me, if pushed, this issue is the one that will be the end of the current liberal/lefty/democrat/communist occupation. Normal people will take a lot of crap from liberals, but they will draw a line when their relationships are being threatened. And that's what people have - a relationship with their radio programs.
This is 2009, not 1939. The media - all the media, the shore-to-shore carpet of media, and the people's knowledge about the media, has become much more sophisticated.
