In this ad Obama accomplishes two things: 1) His national security/foreign policy bona fides, by pointing out his work to track down loose nukes = preventing nuclear terrorism and 2) That he can work across party lines, showcasing his work with Republican Senator Dick Lugar–a respected foreign policy elder statesman–on this issue (and from Indiana–a state that Obama happens to be targeting to turn from red to blue this election).

The ad isn’t overwhelming, but it doesn’t need to be–it accomplishes what it sets out to do.
