Tom Sullivan is incredibly boring.
Hedgecock does a good job but lacks the charisma of Rush. He is probably better informed and can argue the issues better than Rush, but lacks Rush's sense of humor.
Walter Williams is _the best_ guest host for Rush.
The worse host had to have been Tony Snow.
The worse one-time host was resident asshole and pompous LA lawyer Bill Handel. Too bad Laura Ingraham will never come close to his show in LA.
