In the aftermath of Super Tuesday and the shake-up in the Republican contest, Kathleen Hall Jamieson, director of the Annenberg Public Policy Center, will join Bill Moyers again tonight to talk about the 2008 presidential campaign.  Jamieson, a regular guest of Moyers during the election season, will discuss how well the candidates are delivering their messages and how the public is perceiving them.  For additional program information, click here http://www.pbs.org/moyers/journal/02082008/profile.html
