Chris Matthews just remarked that the crowd is applauding his rebuke of the GOP.  Which explains why they were entirely silent when he rebuked the party or talked about any non-doctrinaire position.  Much like last night, I don’t think that they watched the same speech that actual people did.  Actually, they probably just watched The Last Starfighter and went “Pew!  Pew!” the entire time while hiding behind couches and throwing pretend neutron-grenades.
