(The Center Square) – Early voting is Wednesday through Friday this week for South Carolina’s U.S. Senate special Republican primary runoff on Aug. 25.

U.S. Sen. Darline Graham and U.S. Rep. Ralph Norman advanced last week in an election attracting just 11.1% of more than 3 million eligible voters. The winner next week will take a spot on the Nov. 3 ballot previously earned by the late Sen. Lindsey Graham.

Dr. Annie Andrews, a Charleston pediatrician, is the Democratic opponent in November and is joined on the ballot by Libertarian Kasie Whitener.

Lindsey Graham died July 11, and his sister Darline Graham Nardone was chosen to fill the remainder of the term.

In last week’s primary, Darline Graham collected 32.8% of the votes – 109,881 of the 335,693 cast. Norman was next at 24.6% (82,627).

They were followed by U.S. Rep. Russell Fry (19.7%), former Gov. Mark Sanford (14.9%), Mark Lynch (5.9%), Danny Ford II (0.8%), Duke Buckner (0.5%), Glenda Gail Parker (0.3%), Sam Shepherd (0.3%) and Mark McBride (0.2%).

Graham was sworn in July 14 and was the immediate choice of second-term Republican President Donald Trump to finish the term and seek the next six years. Norman, finishing his fifth term in the U.S. House of Representatives, was unsuccessful in June running for governor.

Neither Fry or Democratic challenger John Vincent faced a primary opponent in the 7th Congressional District. Fry said when filing for the upper chamber he would continue the campaign if unsuccessful in the special primary.

Sanford had started a campaign for the 1st Congressional District seat but unofficially withdrew before the primary, though he still appeared on the ballot and was fourth. He’s known from his time as governor, as a U.S. House member, and his presidential bid in 2019 that was short-lived from a Sept. 8 announcement to a Nov. 12 suspension of the campaign that never restarted.

In the June primary, Lindsey Graham easily bested five challengers including second-place Lynch (56.8%-28.9%).
