Interim Senator Darline Graham and Representative Ralph Norman lead the pack in South Carolina’s Republican Senate primary, as revealed by a recent survey. With voters heading to the polls soon, the poll conducted on July 21 shows Graham with 20.8 percent support from likely Republican primary voters, followed by Norman at 16.9 percent. The survey indicates no candidate has reached a majority, suggesting the August 11 primary may lead to an August 25 runoff.
This early glimpse into the race comes after President Donald Trump’s July 17 endorsement of Graham, prompting her to campaign for a full Senate term. Newsweek reached out to the campaigns of Graham and Norman regarding their strategies.
A Compressed Race Following Lindsey Graham’s Passing
The special election arose from the July 11 passing of long-time GOP Senator Lindsey Graham, a close ally of Trump. Governor Henry McMaster appointed Darline Graham as his successor. Initially seen as a temporary choice, the endorsement shook up the dynamics, inspiring Graham to pursue her brother’s legacy.
Graham leads in the polls, but the numbers remain uncertain. The survey indicates 17.8 percent of voters are unfamiliar with her, and 31.3 percent have yet to form an opinion. Resonance Media Services conducted the poll among 600 likely Republican primary voters, with a margin of error of 4 percentage points. Graham’s slim lead falls within this margin, leaving analysts cautious about predicting a definite front-runner.
Norman Positions for a Runoff
While trailing slightly, Norman remains strategically positioned should the primary reach a runoff. The poll reveals Norman’s strong favorability and potential as a second choice for many voters. Despite Graham’s endorsement, Norman, an outspoken Trump supporter and third-place finisher in the gubernatorial race, continues his campaign.
Support across other candidates remains dispersed. Lieutenant Governor Pamela Evette holds 9.6 percent, with Representative Russell Fry and businessman Mark Lynch each at 7.2 percent. Former Governor Mark Sanford polls at 7.1 percent, Representative Nancy Mace at 2.8 percent, and attorney Duke Buckner at 0.9 percent. Sanford’s entry to the Senate race occurred after the survey, while Mace exited the race recently.
Split Conservative Endorsements
Prominent party figures are divided in endorsements. Graham has backing from Senator Tom Cotton, with Senate Majority Leader John Thune offering praise without a formal endorsement. Meanwhile, Norman gathers support from Senators Rick Scott and Mike Lee, showcasing a split among key conservative leaders.
General Election Outlook
As Republicans navigate the tense primary, Democrat Annie Andrews, who secured her nomination earlier, is preparing for the November general election. Andrews suggests the tight Republican primary could benefit Democrats. Political expert Justin Vaughn from Coastal Carolina University remarks that South Carolina remains a solidly Republican state, and the seat is anticipated to remain under GOP control.
Trump won South Carolina by 18 points in 2024, and Democrats last held a Senate seat there in 1998. With the August 11 primary drawing near, it’s one of the nation’s most watched elections, marked by voter volatility and rapid developments.
