COLUMBIA, S.C. (AP) — Joe Biden scored a thundering victory in South Carolina’s Democratic primary on the strength of African American support, a decisive win that could force moderate rivals out of the race and blunt the rise of progressive leader Bernie Sanders. Biden’s win Saturday came at a perilous moment in his 2020 bid as he needed an emphatic rebound after underwhelming performances this month in Iowa, New Hampshire and Nevada. The race now pivots to the 14 states from Maine to California that vote on Tuesday in what effect will be a national primary. Biden won about three times as many delegates in South Carolina as his nearest rival. Sanders claimed a distant second place, a loss that gave a momentary respite to anxious Democrats who feared that the democratic socialist would finish February with four consecutive top finishes that would make it difficult for anyone to overtake him.
