From a comment I wrote on another journal:
Listening to Sean Hannity as I drove across Wyoming last weekend, I think I realized the key to right-wing talk shows:
The host never admits they are, were, or could be wrong. A guest on, say, Charlie Rose's or Bill Moyers' shows is there to educate the listeners and the host. But a guest on Glenn Beck's or Rush Limbaugh's shows are there either to agree with the host or for the host to browbeat and contradict.
It's a great business move: If you present yourself as infallible and your listeners believe it, they'll be very loyal listeners, ripe for advertisers.
Contrast this to a prominent radio host on the left of the spectrum like Amy Goodman of Democracy Now
. She shares her point of view through selection bias, inviting guests whose message she wants to spread and letting listeners hear it in a new voice each day. When she has a guest she strongly disagrees with (she hosted Lou Dobbs a few years ago), she sticks to the question format, though with more points and barbs than folks she likes. But she never outright tells a guest they're wrong or screams at someone to get off the air
