September's Democratic presidential debate has been narrowed to one night only, as more candidates have called it quits altogether.
Ten candidates are on stage for three-hour event hosting by ABC News and Univision: former Vice President Joe Biden; New Jersey Sen. Cory Booker; South Bend, Ind., Mayor Pete Buttigieg; former Housing and Urban Development Secretary Julián Castro; California Sen. Kamala Harris; Minnesota Sen. Amy Klobuchar; former Texas Rep. Beto O'Rourke; Vermont Sen. Bernie Sanders; Massachusetts Sen. Elizabeth Warren and entrepreneur Andrew Yang.
It's the third debate of the campaign and the first time that Biden, Warren and Sanders are all together.
Who will be the main target, what does it mean and what do the candidates stand for? Follow NPR Politics reporters for live analysis and fact checks.
