South Carolina Democrats chose their challenger to U.S. Sen. Tim Scott in a night of primary, runoff and special election contests in seven states.
State Rep. Krystle Matthews defeated author and activist Catherine Fleming Bruce in a Democratic primary runoff.
With 75% of results reported, Ms. Matthews was ahead of Ms. Bruce 56% to 44%.
Ms. Matthews now faces a tougher battle on the November ballot against Mr. Scott, the Senate’s only Black Republican member. Mr. Scott remains popular with voters in the deeply conservative state and was elected to his first full term in 2016 with 60% of the vote.
