Dan Rather will never resign. His arrogance will never allow that.
No, but he can be forced to if CBS ratings go in the tank.
True, he won't resign. He will continue to say, "It's not about the documents, it's about the charge." He will hope that if he continues to deny, he can change the perception, ergo, the truth. He will deny this to the VERY END, even if he's kicked upstairs.
But this is out of control for him now. He will continue to hunker down and hope the news cycles will make this fade away.
That might have worked five years ago, but since then there's been a revolution:
If things get to hot, Dan will announce his retirement from C-BS and he will become their scapegoat.
