Now, can someone please explain to me why there's no Kerry ad simply juxtaposing the current words of the Swift Boat liars and statements made by the same people on other occasions? You know -- an ad something like this?

In an unpublished interview in March 2003 with Mr. Kerry's authorized biographer, Douglas Brinkley, provided by Mr. Brinkley to The New York Times, Roy F. Hoffmann, a retired rear admiral and a leader of the group, allowed that he had disagreed with Mr. Kerry's antiwar positions but said, "I am not going to say anything negative about him." He added, "He's a good man."

In a profile of the candidate that ran in The Boston Globe in June 2003, Mr. Hoffmann approvingly recalled the actions that led to Mr. Kerry's Silver Star: "It took guts, and I admire that."

George Elliott, one of the Vietnam veterans in the group, flew from his home in Delaware to Boston in 1996 to stand up for Mr. Kerry during a tough re-election fight, declaring at a news conference that the action that won Mr. Kerry a Silver Star was "an act of courage." At that same event, Adrian L. Lonsdale, another Vietnam veteran now speaking out against Mr. Kerry, supported him with a statement about the "bravado and courage of the young officers that ran the Swift boats."

"Senator Kerry was no exception," Mr. Lonsdale told the reporters and cameras assembled at the Charlestown Navy Yard. "He was among the finest of those Swift boat drivers."

Those comments echoed the official record. In an evaluation of Mr. Kerry in 1969, Mr. Elliott, who was one of his commanders, ranked him as "not exceeded" in 11 categories, including moral courage, judgment and decisiveness, and "one of the top few" - the second-highest distinction - in the remaining five. In written comments, he called Mr. Kerry "unsurpassed," "beyond reproach" and "the acknowledged leader in his peer group."

Is the Kerry campaign afraid of seeming to attack veterans -- any veterans? If so, haven't the liars and their backers already gone way over that line?

(By the way, I think a clip of Swift boat liar Van Odell saying "I do not have a single document" might work nicely in an ad of this kind.)
