Liberals, would you rather listen to AirAmerica or Rush Limbaugh?

Personally, as a left leaner, I would rather hear Limbaugh. I believe we liberals don't like the talk radio format. I've heard that half of Limbaughs audience is comprised of people who do not consider themselves "conservatives". I'm one of them. Yet these guys always use their high ratings to prove that their audience is full of people who agree with them.
