The damage would have been to Kerry. They probably delayed the story at Kerry's request. Imagine how Rathergate and then Spygate would have looked to most people: an out of control President? Or an out of control press out to get the President?
Or an out-of-touch Rat party with no clear how to secure the nation in the face of an actual threat?
And considering the polls and the public's response to the "scandal" of the NSA eavesdropping, the release of this info would only have HELPED Bush (unless it had been done the weekend before the election so that Bush wouldn't have been able to explain the program as he has done so far)
I just don't see the outrage by most people about this...When they realize that the eavesdrops were on AL Quada terrorists who are speaking to people here, it's a no brainer.
