With the 2012 campaign season moving from primary to election mode, Bill Moyers invites back to his studio master media decoder Kathleen Hall Jamieson for a look at the role media misinformation will play in the Obama vs. Romney TV ad slugfest. Jamieson runs the Annenberg Public Policy Center of the University of Pennsylvania, including the sites FactCheck.org and FlackCheck.org. In this edition of Moyers & Company, Jamieson and Moyers discuss the sharp increase in deceptive advertising in the 2012 race and equally alarming new obstacles to campaign ad transparency. In addition, Moyers talks to RoseAnn DeMoro, who heads the largest registered nurses’ union in the country, and who is championing the Robin Hood Tax, a small government levy the financial sector would pay on commercial transactions like stocks and bonds.
