FILE - In these Sept. 2012, file photos Republican presidential candidate Mitt Romney, left, boards a plane in Denver, Colo, and President Barack Obama gets off a plane in Tampa, Fla., during an intense campaign in competitive states. Obama and Romney each have a specific mission for the string of three debates that starts Wednesday night, Oct. 3, 2012. Obama, no longer the fresh face of 2008, must convince skeptical Americans that he can accomplish in a second term what he couldn't in his first: restore the U.S. economy to full health. Romney, anxious to keep the race from slipping away, needs to instill confidence that he is a credible and trusted alternative to the president, with a better plan for strengthening the fragile economy.
