It's round two tonight at Hofstra University in Hempstead, N.Y., where President Barack Obama and former Massachusetts Gov. Mitt Romney meet for the general election debate.
The candidates first went toe-to-toe earlier this month in Denver, Colo. A CNN poll found 67 percent of likely voters said Romney won the debate.

But tonight's debate will be different--a town hall-style debate where about 80 uncommitted voters will submit questions about domestic and foreign policy for the candidates to answer.
