HEMPSTEAD, New York (CNN) - President Barack Obama and Republican challenger Mitt Romney face off Tuesday in the second of their three debates, this one in a town hall-style setting in which they'll take questions from likely voters.
The stakes couldn't be higher: Obama must get his campaign back on track after a poor performance in the first debate that left Democrats demoralized and Obama's lead evaporating both in national polls and those in key battleground states. For Romney, who polls among voters showed won the first debate overwhelmingly, a second strong performance would boost his momentum going into the third debate next Monday and the final two weeks before Election Day.
