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 hosted by ABC News and Univision, beginning at 8 p.m. ET. It's the third debate of the campaign and the first time that former Vice President Joe Biden, Massachusetts Sen. Elizabeth Warren and Vermont Sen. Bernie Sanders are all together.
