Most intelligent people, in my experience, and people who have well-rounded, fulfilling lives, are more interested in listening to music on the radio than to preaching, rabble-rousing, etc.

That, sadly, is the reason why there is a larger market for sensationalist radio "talk" than for any sane, even-handed discussion of political issues. Those who might constitute an audience for intelligent and balanced political talk generally have better things to do with their time than to sit foaming at the mouth as they dote on the words of some alarmist jackass
