olbermann is an attack dog.
these other putzes are guard dogs.
you see, putzes will repeat anything and will never question obama. Olbermann? he's built to attack. He attacked the shit out of bush (usually with evidence of wrongdoing) and he was doing the same to obama when they booted him.
When the repubs get shit together and win the presidency, msnbc will cut these obedient putzes and hire another ATTACK dog. maybe the 'triumphant return of olbermann!'
guard dogs and attack dogs. now ya know
