That's kind of like saying, "One Catholic came out against birth control. One --Of course, that Cathollic's the pope."
Only if every other Catholic favored birth control and the vast majority didn't think that guy who says he's the Pope actually is the Pope. Kristol's an unstable commentator who swings with the DC winds -- often in bizarre directions. Any so-called "neo-con" I respect favors Rumsfeld.
