Obama as Publicist-in-Chief

President Obama appeared on no fewer than five media outlets over the weekend, trying to get the word out about his health care initiative, the war in Afghanistan and his missile defense plans overseas. For a look at the impact of the president’s media blitz, we speak to Kathleen Hall Jamieson, director of the Annenberg Public Policy Center at the University of Pennsylvania.

Tonight the president will trade in his policy-wonk hat for (hopefully) more comedic fare when he appears on “The Late Show with David Letterman.” We are creating our own Top 10 list of things the president should not say on the show. Send us your suggestions and we’ll make a list of the funniest.
