FILE - In this July 13, 2012, file photo, President Barack Obama gestures during a campaign stop at Green Run High School in Virginia Beach, Va. Nearly four years after Barack Obama was elected to the most powerful office in the most powerful country in the world, the question remains: Who is he? This is a man who seemed to come out of nowhere. He had served seven years in the Illinois state Senate, and less than four years in the U.S. Senate _ a meager political resume, augmented by a stirring speech at the 2004 Democratic National Convention.
