That's not quite what the memo said. That, if true, would be a statement of fac, demonstrable at least in theory. However what the memo actually said was that the distortions are a central part of Bush's campaign, but the even more extensive distortions of the Kerry campaign are not a central part of his campaign. That's a judgement call, and not direct demostrable. It's also, IMHO not true.
Time for the SwiftVets/POWs "October Surprise.".
Are you confident that they have one?
