When you mention swiftboat ads, you might also mention the Swiftboating by Dan Rather and the rest of liberal media, if not complicit Democrats, when they attacked Bush with a forged letter allegedly from Bush's National Guard commanding officer, just 2 weeks before the 2004 election.
While CBS and Rather did a piss poor job of evaluating the authenticity of the document, Marion Knox, the 86 year old former secretary was found who also said the document was fake. She did however say she remembered doing a similar document with roughly the same information in it. She also said Bush was unfit to serve as President and was selected, not elected.
So much for "swift boating". When the secretary who typed up the documents says the documents were fake but the INFO was spot-on. Sounds like a classic Rove deflection/distraction tactic to me. (see Rove bugging his own HQ and accusing the Democrats).
