Nine presidential Democratic candidates plan to meet Sunday for the second of two debates sponsored by the Congressional Black Caucus Institute (search) and FOX News, but it's not the same nine that graced the first debate last month.

Since the Sept. 9 debate at Morgan State University in Baltimore, Florida Sen. Bob Graham (search) has dropped out of the race, and retired Army Gen. Wesley Clark (search) has jumped into the fray.

Taking much of the buzz from the frontrunners, Vermont Gov. Howard Dean (search) and Massachuetts Sen. John Kerry (search), Clark has recently laid out positions on Iraq, tax cuts and the economy that are sure to be challenged in Sunday's debate.

Polls show Clark running about middle-of-the-road in the first caucus state of Iowa, where he has decided to forego campaigning, but a New York poll shows Clark running third to Dean and Connecticut Sen. Joe Lieberman (search), who ranked first in the Marist Institute poll. Clark has also been polling near the top in New Hampshire and nationally.

Viewership of the Sept. 9 debate was the highest for cable television in the time slot for that night, beating its competition by 2 to 1.

"It is very encouraging that so many American voters watched the debate and received the information that will engage them in this presidential campaign and help them to make an informed choice as voters in the critical presidential election next year," said CBC Chairman Elijah Cummings, D-Md.

Sunday night's debate will air live on FOX News Channel at 8 p.m. EST. Don't miss it!
