FILE - In this Saturday, May 5, 2007 file photo, Pat Robertson, right, the founder of Christian Broadcasting Network and the chancellor of Regent University, sits with Republican presidential hopeful Mitt Romney, the former governor of Massachusetts, before Romney delivers the commencement address to the 2007 graduating class of Regent University in Virginia Beach, Va. How unthinkable it was, not so long ago, that a presidential election would pit a candidate fathered by an African against another condemned as un-Christian. And yet, here it is: Barack Obama vs. Mitt Romney, an African-American and a white Mormon, representatives of two groups and that have endured oppression to carve out a place in the United States. How much progress has America made against bigotry? (AP Photo/Gary C. Knapp)
