I remember it as a kind of retirement gig for has-been liberals. Phil Donahue for example.
I used to watch Imus in the Morning. Dan Abrams, Rita Cosby, Michael Savage, and Joe Scarborough all had decent Prime Time shows.
Actually, Michael Savage had a weekend afternoon show. It only lasted three weeks before they fired him.
But Alan Keyes did have a weeknight show for a year or two.
