CNN Chief Political Correspondent Candy Crowley will moderate tonight's debate.
President Obama is focused on trying to make up lost ground after a lackluster performance in his first debate. Democrats hope to see the president bring his stump speech criticism of Romney to the debate hall.
Meanwhile, Romney has had nearly two weeks to watch his post-debate support grow. A new CNN poll of polls that averages secen national surveys finds Romney leading President Obama by one point.
In today's debate, there is a new twist: the candidates will talk with undecided voters, making it more important than ever to win over the crowd.
