Good question, if this was all there was, but remember this was just the opening shot. They wanted to sow doubt in the mind of the American voter, where was Bush, why didn't he take his physical.
The next round was Kitty Kelly's book. Suggestion of drug use. Later they were going to try and tie this all together, perhaps with a late Octomber surprise of their own.
So this nothing story (Bush in the ANG, was just one piece.
By ending it as we have, the other pieces can not be played, or like the Kitty Kelly book, be overshadowed by this story. Speaking of which, Kitty Kelly's book is so yesterday.
As someone else observed, this is going to innoculate the President from a lot of cheap charges coming out over the next few weeks. Unless someone has a signed document by Bush himself, nothing the MSM says about President Bush is going to be believed.
The truly Orwellian thing about all of this is the DNC and shills will just keep saying all this crap even though it has been fully discredited.
