A good comment on the "swift boating of John McCain" is here.
I must disagree with charges that McCain is being "Swift Boated." For this to be a "Swift Boating," people who stayed at the Hanoi Hilton would have to say that McCain was lying about what he did there -- or perhaps that his repeated claims that events there were "seared, seared" in his memory are false, and he was never actually there at all -- and those people would have to be telling the truth.
Or as a friend of mine puts it:
swift boat (v.i.): to tell the truth about a Democrat.
As Glenn would put it: Heh.
