South Carolina Republican Primary Underway to Fill Vacated Senate Seat

2026-08-11

The BareStory

South Carolina Republican voters are casting ballots on Tuesday, August 11, 2026, in a special primary election to fill the U.S. Senate seat vacated by the death of Lindsey Graham. Senator Graham died in July 2026 at age 71 after a sudden illness. His sister, Darline Graham, was appointed to the seat following his death and is now campaigning to retain the position.

Darline Graham, who previously served as commissioner of the South Carolina Commission for the Blind, is one of ten Republican candidates in the race. Her competitors include former Governor Mark Sanford, U.S. Representatives Ralph Norman and Russell Fry, and businessman Mark Lynch. If no candidate secures more than 50 percent of the vote, the top two finishers will proceed to a runoff election on August 25. The eventual Republican nominee will face Democratic candidate Annie Andrews, a pediatrician, in the November general election.

Darline Graham has campaigned on a platform centered on domestic economic issues, stating that reduced government spending is necessary to lower the costs of groceries, gas, and healthcare. She has also voiced support for ending the Senate's legislative filibuster and fully backing Donald Trump's agenda, having received his endorsement. However, some local party officials, including Berkeley County Republican Party chair John McGrath, have expressed reservations about her rapid transition, stating that voters currently know little about her.

The South Carolina election is part of a broader multi-state primary day, with voters also heading to the polls on Tuesday in Wisconsin, Minnesota, Alabama, Connecticut, and Vermont.

How it may affect me

As a U.S. reader:

• In the short term, voters in South Carolina and five other states are deciding primary nominees, with South Carolina voters potentially facing a runoff election on August 25 if no candidate wins a majority.

• In the long term, the election of a candidate who supports ending the legislative filibuster could lead to either a more streamlined federal lawmaking process or the weakening of minority party protections in the Senate.

• In the long term, the implementation of the proposed fiscal platforms could either lower household costs for groceries, gas, and healthcare through reduced government spending, or reduce funding for vital public safety nets and healthcare access.

• The race's outcome will determine whether the vacant Senate seat is filled by someone offering ideological continuity and legacy or someone focused on alternative public health and social programs.
