Of course, the leftists carefully omit explaining why they believe Bush knew the info was false when it was presented. He didn't, in fact - he went with the strong recommendations of his advisers on both sides of the aisle, the vast majority of whome supported the conclusions at the time, for good reason.
There were literally hundreds of reports saying that Saddam had WMDs, was collaborating with Al Qaeda, etc., and a half dozen saying maybe he didn't. Now the Bush-bashers are screaming that he "knew" the hundreds were wrong and the few were right... again, carefully omitting any explanation of how he could have known.
This has been pointed out to the leftist hysterics many times, of course. Looks like enough time has passed since the BUSH LIED crowd was last smacked down and sent packing, that they think people will have forgotten, and they can bring up all their old, discredited accusations again and pretend they have a legitimate argument. The result is the standard circle jerk we're seeing here, with leftists earnestly telling each other how right they are, and few bothering to re-debunk them for the nth time.
Standard tactic of the left. No wonder they hate the "new media", including the internet... it won't forget what they want it to forget.
