Charlie Sykes is Milwaukee's other big conservative radio show host. You probably know of Belling, who has been guest-hosting for Rush a few times over the past few weeks.
Sykes is intellectually solid and has the kind of insight into things that Rush has. Unfortunately, Sykes doesn't have the punch. He's not terribly stimulating to listen to, so you have to want to hear what he has to say. I like him a lot though.
