President Barack Obama returns to the state today with a visit to Iowa State University in Ames. Obama is returning to Iowa just less than two weeks after he spent three days on a bus tour campaigning in the state discussing renewable energy and his economic policies.

This trip is part of what his campaign calls the president’s college tour. It begins with the stop at Iowa State, where he will talk about his proposal for a college tax credit, and will also include stops at Colorado State and the University of Virginia.

The president will speak this afternoon on the school’s central campus near the campanile. That will require closing several roads and buildings for several hours, and some classes will be moved to other buildings. The president also plans to stop in Des Moines and Sioux City on Saturday.
