It wasn't enough to get the Senate to impeach him--but it MIGHT have made a difference in the 1996 race. At the very least--this might put Kerry on defense at a time he was counting on going on offense.
Of course, to me, he's always been pretty "offensive"!
I have a feeling that this is going to be a hoax perpetrated to get multiple hits on a web page. There has been no movement by the Kerry campaign to squelch the story or any of their people out at least saying "there is no story". In the end this will be a silly joke just to get our hopes up and a few hits to powerline's web page.
