President Donald Trump’s endorsement of Darline Graham to succeed her late brother in a U.S. Senate special primary has triggered a conservative backlash in South Carolina. An Emerson College poll shows Ralph Norman leading the August 11 primary with 22 percent support, while Graham follows closely at 19 percent.
The political landscape in South Carolina shifted abruptly earlier this month following the sudden death of longtime U.S. Senator Lindsey Graham. In response, South Carolina Gov. Henry McMaster appointed the late senator’s sister, disability services worker Darline Graham, to fill the seat as an interim placeholder through the end of her brother’s term in early 2027. But rather than quietly serving out the remainder of the term, Darline Graham announced an unexpected campaign for a full six-year term, securing an immediate endorsement from President Donald Trump in the upcoming Republican primary.
That backing has not translated into smooth sailing. Influential conservative activists and local party members across the state have voiced frustration, arguing that the endorsement relies heavily on family ties rather than a proven conservative record. Darline is really in for a dogfight,
a Republican official told the Washington Post.
Polling Figures Show a Tight Field Heading Into August 11 Primary
An Emerson College Polling and Nexstar Media survey conducted July 28–29 among 500 likely Republican primary voters reveals a fractured electorate with a high degree of undecided voters just weeks before ballots are cast. U.S. Rep. Ralph Norman leads the crowded field with 22 percent support, followed by Darline Graham at 19 percent, U.S. Rep. Russell Fry at 12 percent, and Mark Sanford at 11 percent, according to Emerson Polling.

With 12 total candidates filing to run in the special primary—including two members of Congress and Sanford, who served as governor from 2003 to 2011—the race is widely expected to head to an August 25 runoff. A quarter of surveyed primary voters remain entirely undecided, though Sanford holds a slight edge among that uncommitted block with 21.2 percent support according to Queen City News.
Voter demographics reveal stark generational divides across the candidate pool. Norman commands strong support from younger voters, drawing 24 percent from those under 50 and 25 percent from voters in their 50s. Conversely, Graham’s base skews older, with 30 percent support coming from voters over 70.
Weighing Trump’s Endorsement Against Foreign Policy and Domestic Record
Trump’s intervention in the race has yielded mixed reactions among the state’s conservative base. While 29 percent of primary voters say the presidential endorsement makes them more likely to back Graham, a majority of 53 percent report that the endorsement makes no impact on their vote, and 18 percent say it makes them less likely to support her.

At the same time, Graham faces scrutiny over her political background and foreign policy positioning. Having never previously held elected office, she has attempted to align herself with the MAGA movement by backing the SAVE Act, touting anti-abortion views, and campaigning to the right of her late brother. However, those credentials have met resistance. Her connection to the hawkish Lindsey Graham poses a potential liability among voters wary of foreign entanglements, even as 56 percent of primary voters strongly support U.S. military action in Iran.
Questions regarding her past political participation have further complicated her pitch. Public records indicate her only recorded political donation went to a female Republican legislator who blocked a total abortion ban in South Carolina, and she did not vote in the 2024 presidential primary.
Economic Pressures Shape Voter Priorities as Debates Loom
Economic concerns dominate the electorate’s focus as candidates sprint toward the finish line. A clear majority of special election voters, 60 percent, rank the economy as the most pressing issue for South Carolina’s next senator, well ahead of immigration at 19 percent, healthcare at 8 percent, and foreign policy at 4 percent.
Voters divide sharply over who carries the blame for cost-of-living pressures. A plurality of 41.6 percent blame former President Joe Biden for high grocery prices, while 32 percent point to President Trump as the primary driver behind current gas prices.
With Senate leaders like National Republican Senatorial Committee Chair Tim Scott and Senate Majority Leader John Thune holding off on formal endorsements, the candidates must make their final impressions directly with the electorate. Nearly 88 percent of primary voters emphasize that candidate participation in a debate before the August 11 primary is important, leaving a narrow window for contenders to define themselves before voters head to the polls.
