COLUMBIA, S.C.—In the next step of a race already on pace to become the most expensive in South Carolina history, U.S. Sen. Lindsey Graham has defeated three little-known GOP challengers, the last marker ahead of a general election face-off with Democrat Jaime Harrison.
Graham, 64, bested fellow Republicans Duke Buckner, Michael Lapierre, and Joe Reynolds in Tuesday’s primary election. Harrison was unopposed in his primary, and two Libertarians and one Constitution Party candidate have also filed to seek the seat.
