President Obama is back in the state this week, visiting a wind turbine manufacturer in Newton. We'll look at how the pending loss of two wind energy tax credits could affect Iowa's economy. Also, a new poll shows the President and Mitt Romney locked in a dead heat over who could fix the economy. Ben's guests are University of Northern Iowa Political Science Chair Donna Hoffman and University of Iowa Associate Political Science Professor Tim Hagle. Iowa Public Radio Chief Correspondent Dean Borg joins the conversation to discuss the 1st District Primary debate held this week in Cedar Rapids between Republicans Rod Blum and Ben Lange. The primary winner faces Democrat Bruce Braley in the November Election.
