South Carolina Sen. Darline Graham and U.S. House Rep. Ralph Norman will advance to a special primary runoff in two weeks, when voters will decide which GOP candidate might take the vacant seat of the late Lindsey Graham. Darline Graham, Lindsey Graham’s younger sister, secured 33% of the vote, with 95% of ballots counted. “I decided to answer the call to serve because South Carolina and President Trump need a leader who’s tough, principled and will fight to advance our conservative values in Washington,” Graham told supporters on Tuesday night.
