Since Halprin's memo came out, ABC now must demonstate that they will show what may in fact help Bush. However, personally, I'm more interested in the tape because I want to see it in case a future attack occurs.
ABC's memo came out right before the townhall debate. Since then Jennings has been complaining about being expected to be "objective" and Koppel has run to the Viet Cong to exonerate Kerry. I don't sense great motivation on their part to redeem their reputation since the reveal of the memo.
