Cumulus is the nation's second biggest radio company (it's gigantic), and they now air Limbaugh and Hannity (syndicated by the biggest radio company--Clear Channel) in about forty or so markets. According to Politico, they are making rumblings about dropping them.
A few notes about this. #1--This could just be a negotiating tactic. #2--Even if they are dropped (including in Chicago--WLS is a Cumulus station), they won't be replaced by anything that cleans the toxic airwaves. Cumulus is talking about adding outlets for the likes of Michael Savage and Mark Levin instead.
That would be like mopping your kitchen floor with a bucket full of oil.
