This is exactly what I just mentioned to a family member of mine. O'Donnell was SUPPOSED to shout him down. Have not read every post on this thread yet, but I must mention, however, that I cannot remember anyone, not even Carville and that's saying a LOT, calling an opponent a "creep". That's just such LOW SCUMBAG-talk to speak on a nationally televised show - incredible. And Buchanan just sat there like a dummy doing absolutely NOTHING. (PLEEEZE Pat, don't sign up to be a Republican again any time soon. We don't want you. You're worthless.)
A lot of people in this thread have been attacking Pat for not "doing something," so I think I need to point something out: The anchor doesn't control the show. That's the producer's job. Plus, it's not even Pat's show; he's just subbing for Scarborough.
If Pat had gone too far in cutting off O'Donnell, it would be Pat looking for a new TV gig in the morning.
