FILE - In this photo combo from file imagery, President Barack Obama, left, speaks at the University of Iowa in Iowa City, in an April 25, 2012 file photo, and Republican presidential candidate, former Massachusetts Gov. Mitt Romney speaks in Chantilly, Va., in a May 2, 2012 file photo. After all their liberal vs. conservative differences are spoken, Obama and Romney sound a lot alike when they are being described by the other guy or his campaign. That leaves voters the challenge of having to sort out what's real and what's been stretched out of proportion. (AP Photo/Carolyn Kaster, Jae C. Hong, File) less
