Obama Speech Circuit and Iowa's Political Geography

President Obama spoke in Galesburg, Illinois Wednesday as part of a swing through the Midwest to talk about the economy.  Host Dean Borg gets an update from that appearance, and talks with Bruce Gronbeck, Emeritus Professor of Communication Studies at University of Iowa about the other speeches the President has been making in recent weeks.  Then, Chris Larimer, Associate Professor of Political Science at University of Northern Iowa explains why the political geography of Iowa heavily favors Democratic Congressman Bruce Braley in his bid to replace U.S. Senator Tom Harkin.
