President Barack Obama and Republican challenger Mitt Romney square off in a town-hall style debate at 9 p.m. EDT at Hofstra University in Hempstead, N.Y.
Obama is expected to be feistier than he was in the first debate, and Romney is expected to employ the energized, somewhat confrontational, style that paid off for him in the earlier clash. Both candidates can be expected to try to engage with the audience members who ask questions.
And, yes, CNN's Candy Crowley says she will ask follow-up questions if need be.
Tomorrow's hot topic? Who won the debate, why and what it means?
Also worth noting Tuesday: Paul Ryan campaigns in Virginia, and first lady Michelle Obama campaigns in North Carolina before heading to the debate.
Vice President Joe Biden has postponed campaign events in Nevada to attend former Pennsylvania Sen. Arlen Specter's funeral. Specter died Sunday from complications of non-Hodgkin Lymphoma.
And then there is this: Elizabeth Warren, Democratic candidate for the U.S. Senate in Massachusetts, will be joined by Sandra Fluke on Tuesday on the campaign trail. Fluke got national attention this past summer when she was called a "slut" and a "prostitute" by conservative commentator Rush Limbaugh after she testified to congressional Democrats in support of national health care policies.
And this: Former U.S. Sen. George McGovern, the Democratic presidential candidate who lost to President Richard Nixon in a historic landslide in1972, has moved into hospice care near his home in South Dakota.
