SELMA, Ala. (AP) An emboldened Joe Biden claimed a trove of new endorsements and campaign cash on Monday in an urgent scramble to rally the Democratic Party s moderate wing behind him and against progressive Bernie Sanders as the Democrats shrinking presidential field raced toward Super Tuesday.

One of Bidens leading moderate rivals, Pete Buttigieg, suspended his campaign Sunday just 24 hours after Biden scored a resounding victory in South Carolina , his first of the 2020 roller coaster nomination fight. Buttigieg and Biden spoke late Sunday night, but it was unclear if Buttigieg planned to endorse the former vice president.

Other Democrats appeared undeterred and vowed to press on, potentially toward a contested convention.

The fast-moving developments came at a key crossroads in the Democratic Partys turbulent primary season. Fourteen states, one U.S. territory and Democrats abroad will vote on Tuesday, which offers almost 10 times more delegates in a single day than have been awarded over the first month.

Fiery progressive Sanders remained the undisputed front-runner. But the rest of the field was decidedly unsettled, even after Bidens South Carolina blowout and the departures of Buttigieg and billionaire activist Tom Steyer.
