I wish I was as optimistic, but the only way he'll be gone by then is if he accepts an official position with the DemonRATic campaign (IMHO, there's a better chance that the Kerry/Edwards ticket won't be intact come October).
That Rather has to address this twice on-air now, means it is still reverberating in the MSM, and hurting CBS. That's good. This story has had legs for 8 days and is still going on!!
Dan Rather is no different from any of us. He takes a sh!t and wipes his ass with toilet paper like the rest of us. If any of us screwed up on the job we would be fired or sued in a heart beat (depending where we are on the totem pole).
We employ him through our consumer dollars. His position assumes a certain amount of public trust. (Okay in an unbiased media) When he abuses that trust, as he has...he has got to go.
The only ones who will see this through to the end is us.
