Tuesday's Democratic presidential debate in Westerville, Ohio, has some key differences from the last three. This time, there is an ongoing impeachment inquiry into President Trump, Massachusetts Sen. Elizabeth Warren is catching up to former Vice President Joe Biden in the polls and businessman Tom Steyer is making his debut to the debate stage.
There will be 12 candidates total in the CNN/New York Times debate, which will air on CNN and on many NPR member stations beginning at 8 p.m. ET. It's the most that have been on stage at once. The candidates who met the October requirements are:
Biden; New Jersey Sen. Cory Booker; South Bend, Ind., Mayor Pete Buttigieg; former HUD Secretary Julián Castro; Hawaii Rep. Tulsi Gabbard; California Sen. Kamala Harris; Minnesota Sen. Amy Klobuchar; former Texas Rep. Beto O'Rourke; Vermont Sen. Bernie Sanders; Steyer; Warren; and entrepreneur Andrew Yang.
