Is William Kristol lying or clueless?

William Kristol opens this article with an outright lie. Referring to Kerry's April, 22, 1971 testimony before the Senate Foreign Relations Committee, he writes, "The American people have never elected president someone who, while serving in the military, chose to testify (in uniform) against a war his country was then waging."

Kerry was discharged from the Navy on March 1, 1970. Yes, he was wearing the shirt from his combat fatigues, which was the de-facto "uniform" of many veterans involved with the anti-war movement. But he most certainly did not testify in uniform while serving in the military. My instinct is to suggest that Kristol might have a clue if he had spent a day in his life in uniform, but I suspect he knows he's lying.
