FILE - In this Wednesday, Feb. 29, 2012 file photo, Republican presidential candidate, former Massachusetts Gov. Mitt Romney and his wife Ann walk past rolls of sheet metal as they arrive at a campaign rally at American Posts in Toledo, Ohio. Will voters in Ohio focus on the revitalized auto industry and unemployment below the U.S. average and regard President Barack Obama as the architect of a hopeful but not yet robust economy? Or will they see government as an obstacle, hundreds of thousands of people still out of work and look to Mitt Romney for the answers? (AP Photo/Gerald Herbert)
