One a day, plus iron

"Air America" was an attempt at the liberal analogue of Rush et al. AFAICT it failed immediately and vanished from the scene. I think they made the mistake of trying to be funny and smart instead of just riling people up by saying "all those people on the other side are scum and should be killed".

Liberals do listen to NPR; it has a pretty good chance of being smart and funny (so presumably people who want that already had something to listen to). But (what with being publicly funded and all) its politics are kept quiet and middle-of-the-road.
