The 10th debate of the 2020 primary season, sponsored by CBS and the Congressional Black Caucus Institute, was just four days before South Carolina's first-in-the-South primary and one week before more than a dozen states vote on Super Tuesday. The Democratic White House hopefuls will not stand side-by-side on the debate stage again until the middle of March. That made Tuesday’s debate likely the last chance for some candidates to save themselves and alter the trajectory of the nomination fight.
