In Newsweek, about a week after the election, this reporter wrote that the Kerry campaign didn't respond effectively to the Swift Boat Veterans for Truth was "because most of what they were claiming was true".
I have yet to see that report repeated anywhere.
That quote came from Vanity Fair editor and writer Michael Wolff, while being interviewed for the never-released Kerry campaign film "In the Bubble." He said that the campaign's real problem with the Swift Vets' charges was that they "were largely true." The movie trailer made it look like Wolff was part of the campaign, but he actually wasn't.
