The second Democratic Party debate is scheduled for Nov. 14 at Drake University in Des Moines, Iowa. It is sponsored by CBS news, KCCI and the Des Moines Register. "Face the Nation" host John Dickerson is lined up to moderate, but will probably be joined by other recognizable faces as the date approaches.

The full list of candidates for that debate are not yet known, but will likely include the five that appeared in Las Vegas on Tuesday evening and possibly U.S. Vice President Joe Biden, who has not yet decided if he will run. His inclusion in the list of of those running would be sure to blow wide open the race for the nomination as a third top pick alongside Vermont Sen. Bernie Sanders and former Secretary of State Hillary Clinton. 

Biden is polling at around 16 percent, which is far behind Sanders and Clinton, who are polling at 27 percent and 46 percent respectively, according to a CBS poll released Sunday. A similar poll released Monday by Reuters suggested that 48 percent of Democrats would like to see Biden run, while 30 percent think he should not enter the race. Independents who were for and against a Biden run were split on 36 percent each. 

“There’s an element of people - they know they like him, but they’re not willing to give him their vote yet,” said Steve Schale, a Democratic strategist in Florida with Draft Biden, a political action committee established to lay the groundwork for a Biden run, to Reuters. Schale said that more voters will eventually back the vice president once he has officially launched a campaign.

Unless someone drops out, former Sen. Jim Webb (D-VA.), Former Maryland Governor Martin O’Malley, and Lincoln Chaffee, a former governor of Rhode Island, make up the rest of the Democratic presidential field.
