When Cronkite was going to retire (6 months out) Roger Mudd was to take his place... Dan threatened to quit unless he was given the anchor chair -- some idiot thought he was too valuable to let go so Cronkite retired early, Rather got the anchor job and Mudd left in a huff. He's been drunk with power since.
By golly, you're right. I had forgotten that whole episode. Thanks for the reminder.
