Williams was the night time show host, a Liberal by definition. He was teamed up with Lionel at one of the stations ‘Battle of The Talk Show Hosts’, and Lionel turned on him that night. He was loudly booed at Ruth Eckerd Hall.
Mark was a great talent, but got into some trouble with the front office for some off the air stuff and soon departed.
It would appear that he changes his positions as the wind blows---kind of like Mitt Romney.
