Corsi would be known as just another visitor from the outer fringe if he had not been the co-author of "Unfit for Command," the book that slimed Kerry's exemplary record as a Swift boat commander in Vietnam. The allegations in that book were discredited, but not before they had been amplified by the right-wing echo chamber to the point where they raised questions in some voters' minds - perhaps enough to swing the election.
It was an abominable trick, but quite remarkable. Kerry's opponent, George W. Bush, had avoided Vietnam by taking refuge in the Texas Air National Guard. Kerry was a decorated war hero, yet somehow his valor and sense of duty were turned into a political negative and used against him.
Kerry's record "exemplary"? He wounded himself and left his men behind, then he slimed them. Nothing in Corsi's Kerry book has ever been proven wrong, despite the claims of these "mainstream" journos. W did not avoid Vietnam (unless you believe Dan Rather and his forged documents)...he asked to be sent on active duty and was turned down...but what does accuracy matter when you're trying to make a political point, eh, Gene Robinson?
In LiberalLand, the SBVFT were "discredited" because the New York Times said they were "discredited".
Not that they ever presented any evidence or arguments to support the assertion...
