Sen. Lindsey Graham (R-SC) has spent more than two decades winning Republican primaries in South Carolina without ever being forced into a runoff, but a sizable bloc of undecided voters could test that streak Tuesday in the state’s primary elections.
A Citadel poll published last week found that 18% of likely Republican primary voters are undecided in the race for the GOP Senate nomination, leaving open the possibility that Graham could fall short of the majority needed to avoid a June 23 runoff against leading Republican challenger Mark Lynch.
The Citadel poll put Graham with 46% of the Republican primary vote, Lynch with 36%, and 18% still undecided. A split GOP vote could force Graham into a second-round contest for the first time since taking office in 2002. Graham won his last primary in 2020 with over 67% of the vote, defeating three GOP challengers.
The four-term Republican entered the race as a clear favorite, armed with President Donald Trump’s endorsement, a massive fundraising advantage, and statewide name recognition built from his over 20 years in the Senate.
Yet the contest has unfolded against the backdrop of U.S. involvement in Iran, which Graham has backed, putting him at odds with some of the party’s isolationist wing.
Graham has been among the Senate’s most vocal advocates of a hard-line approach toward Iran and has strongly backed the Trump administration’s military campaign. The longtime senator told his constituents in March to “send their sons and daughters to the Mideast.” He has also framed rising costs for consumers as a result of the Iran war as “consequential,” but necessary to stop Tehran from having a nuclear weapon.
That stance has drawn criticism from several Republican challengers in the crowded field, including Graham’s main opponent, Lynch.

Lynch has taken a hard-line “America First” approach and accused Graham of abandoning the idea that Trump centered his second campaign on. Lynch, who has a business background, is backed largely by the Trump opposition wing of the GOP, with endorsements from several ex-administration officials such as former National Counterterrorism Center Director Joe Kent and former Border Patrol commander Gregory Bovino.
Trump signaled he was aware of how Graham’s Iran war stance could affect his performance in the primary and joined in during a tele-rally Monday night. Trump told voters that the United States would win “over the next two weeks, when we declare total victory,” and touted Graham’s backing.
