The Kerry-letter-to-Bush quote is itself a flatout LIE. Bush/Cheney & the RNC - plus Bush & Cheney themselves - only praised Kerry's service. This too disqualifies the poseur, John Kerry.
Hanoi Johns election committee supports the MoveOn and DU, so they assume that the Swift Boat Vets are an arm of the RNC.
Democrats are so used to playing dirty politics and ignoring the law that they just assume everyone does it.
