I had thought, though (and I confess that it's been a while since I first became aware of the See BS marble promotion system), that when you became an anchor, you received a new bag of marbles.
As anchor, everytime you aired an inaccurate, biased, and factually-slanted story designed to defame or slander a Republican President, Senator, or Governor, See BS took one of the marbles from your bag, and gave you instead a picture of an old bag -- someone like Helen Thomas.
It's clear to me that Dan Rather a long time ago lost all of the marbles See BS gave him when he became anchor.
His current state of dementia, I think, can only be attributed to having a collection of pictures of a variety of old bags.
By jove, I do believe you're on to something there. Rather (no pun intended) quickly, my imagination fills the wall of his office with pictures. I'm seeing faces from the Senate, the House of Representatives, and several major newspapers.....no end of candidates. Is it any wonder he sailed over the edge?
