Analysis: Barack Obama must say 'I believe' No President - not me or any of my predecessors could have repaired all the damage in just four years. But conditions are improving and if you'll renew the President's contract you will feel it," he said, before staring directly into the eyes of America, and solemnly adding: "I believe that with all my heart." That last line was delivered with the fervor of a master political preacher-man: "I believe," he said, as an invitation to weary voters to share his faith that after four years of rising net unemployment and falling incomes, a shining city really did lie over the brow of the next hill. Four years ago, Mr Obama too conveyed that sense of belief; on Tuesday he needs to rediscover it. Instead of looking weighed down by the grim realities facing America - rising global competition, ballooning debts and demographic crunches - he must fix his eyes on a brighter horizon. Election politics is not really a game of policy and statistics, it is a profession of faith; and right now it is Mr Romney who is doing a better job of pedaling hope, a commodity that Mr Obama so famously monopolised in 2008. "Walk with me," says Mr Romney, "and I will raise your incomes, cut your taxes and provide you jobs on which to build future foundations." Attempting to tear a piece out of Mr Romney, or pin him as a heartless plutocrat is not enough. Mr Romney already exploded that (Democrat-created) myth in Denver by showing himself to be a reasonable and raring-to-go candidate for president. No, the passion that Mr Obama needs to show is not a desire to destroy his opponent but a determination to build up a new future, to help America look ahead in difficult times. He must say "I believe," and he must sound like he means it.
