They say what people are thinking

“Why is there a market for [right-wing radio talk shows]?” Hugh Hewitt asked just-retired Wash Post writer Thomas Edsall, who responded:

Because the Democratic Party and liberals have, through a lot of whatever you want to call it, politically correct and other values and programs, made themselves highly vulnerable to criticism that is difficult to voice in the workroom, because it's kind of verboten. But on talk radio, you can say a lot of things that you think and feel,” said Edsall.

That otherwise you can’t say in lots of places.
