Rep. Nancy Mace, R-S.C., is the first in what could be a crowded field of candidates expressing interest in the now-open Senate seat after Sen Lindsey Graham, R-S.C., died suddenly over the weekend.

Graham was seeking reelection at the time of his death and was due to square off against Democrat Annie Andrews in the general election this November, in a race the Cook Political Report with Amy Walter had labeled “Solid R.”

A person familiar with Mace’s thinking, who spoke on condition of anonymity, said she is “strongly considering” running for the seat and would be out with polling on Monday. 

Mace, who has represented South Carolina’s 1st congressional district since 2021, launched a campaign for governor but lost in the Republican primary in June.

“South Carolina lost a giant last night. For more than three decades, Lindsey Graham gave everything he had to this state and this country, from the Air Force to the United States Senate,” Mace wrote on X on Sunday. “We did not always agree, but no one ever questioned his love for South Carolina or the fight he brought to every room he walked into.”

According to South Carolina state law, Gov. Henry McMaster will need to hold a special primary election on Aug.11 the replace Graham on the November ballot. The filing period for that primary will open July 21.

Meanwhile, McMaster has the authority to appoint a candidate to fill Graham’s current role. Punchbowl News reported that Rep. Joe Wilson, R-S.C., is interested in the interim appointment and would run for a full term.
