This is just another demonstration of how much the Democrats love the "Saddam didn't have WMDs" meme. Having spent part of their professional lives saying that Saddam had WMDs, the Democrats, for political reasons, want the public to believe that they never existed. The Democrats evidently believe that the public is stupid enough to fall for this, that the public has no memory that goes past yesterday.
Unfortunately, most of the democratic base CAN'T recall what happened yesterday, and has an attention span measured in RPM's.
