In her latest Op-Ad column for The Nation, Leslie Savan examines the seeming contradictions in McCain's campaign, including his ads.

The column starts with this observation: "Lots of folks have noticed John McCain's tendency to flip-flop during the presidential campaign, but over the past week he's sort of burst the sound barrier on self-contradiction, like the verbal Top Gun he is. In fact, he has so loosed the surly bonds of consistency that you've got to start wondering if there's some deeper meaning behind the constant double-talk."
