I would not be a bit surprised if this administration isn't holding out on a whole bunch of evidence. Being that GWB is considered a great poker player, my guess he is holding a strong hand and waiting for these leftist in the media to be screaming for the evidence and making all kinds of outrageous claims like "Old Scores", "Skull & Bones Society", "Carlisle Group", "It was all about Oil", "Haliburton" and the always handy "After all, he tried to kill my Dad" and then dump the bomb shell on them.
Remember, this is the guy they have been mis-underestimating from day one and since day one, he has been making them look like fools. My money is on George W. Bush.... IT'S A SAFE BET :-)
