Senator Darline Graham (R-S.C.) defeated Representative Ralph Norman in Tuesday's Republican primary runoff with 52 percent of the vote, holding her seat despite President Donald Trump's appearance at a Myrtle Beach rally on Aug. 21, 2026.
The narrow margin revealed cracks in South Carolina's Republican base. At Norman's election night rally, attendees booed Trump's name when it was mentioned—a stark visual of the divisions roiling the party.
Democratic strategist Chuck Rocha seized on the result as an opening. He argued that 52 percent in a GOP primary, even with a presidential endorsement, signals unhappiness within the Republican base. "A lot of them won't. The majority of them won't. But if 10 percent of them do this, place sits in play," Rocha said, referring to the possibility of Norman voters defecting in the general election.
Rocha pointed to a historical pattern: six years ago, Sen. Lindsey Graham (R-S.C.) won his own primary with less than 50 percent, with an opponent capturing 40 percent. The trend suggests vulnerability has haunted South Carolina Republicans.
Democrats have long written off South Carolina as reliably red. But Rocha now believes conditions have shifted enough to make a play for the seat against Graham in the general election. He noted that Democrats have flipped 25 Republican seats in special state house elections nationwide while Republicans have flipped none—a sign, he said, that the political environment has changed since the last effort to unseat Lindsey Graham six years ago. Republicans control the government, he argued, a liability that creates openings.
Rocha drew a parallel to a race in Texas, where he described a Republican running "neck-and-neck with a Democrat in the polls." Even a small percentage shift from Republican voters, he suggested, could flip the race.
Republican strategist Matt Mowers dismissed the theory. He said he would "love to see Democrats dump millions and millions of dollars into deep red South Carolina," noting that a similar gambit against Lindsey Graham six years ago failed. He predicted Norman's voters would not support Democratic candidate Annie Andrews in the general election.
