What major cities don't have a consistant conservative radio voice in them? I'm not aware of any.
From all that I've read, conservatives have a vastly larger presence on radio than "liberals."
What I may not have made clear is that I wasn't referring to "talk radio" but simply the day to day banter on the music stations. THAT is unusual. If anything, it seems that with most DJ's in most cities, if they say anything at all, lean liberal.
