After Senator Lindsey ‌Graham died on July 11 at age 71 from a heart ailment, Governor Henry McMaster appointed his sister, Darline Graham, to serve the remainder of his term, ‌which expires in January. Some Republicans say Darline Graham is a fitting ​caretaker for her brother's seat but oppose Trump's push to elect her to a full term, arguing voters should choose from a field that remains crowded despite the president's endorsement. U.S. Representative Nancy Mace, a Republican who ran unsuccessfully for governor, said South Carolina's conservative voters were upset by the president's endorsement.
