FILE - In this Sept. 22, 2012 file photo, President Barack Obama speaks at a campaign event in Milwaukee. Six weeks from Election Day, President Barack Obama’s campaign has momentum _ and a big case of the nerves. At the campaign’s Chicago headquarters, aides are relishing in polling that gives the president an edge in key battleground states. But they also warn that there’s still plenty of time for the race to change course. And even as the Democratic team considers making a late play for traditionally Republican Arizona, they know that the outcome of three presidential debates with Republican Mitt Romney could shake up their overall strategy.
