Senator Lindsey Graham of South Carolina successfully sidestepped a potentially challenging runoff on Tuesday night, despite facing five Republican opponents and criticism for his unwavering support of the war in Iran.
The Associated Press announced Graham’s victory at 8:57 p.m. ET.
Although South Carolina is a solidly Republican state, there was some uncertainty leading up to the primary about whether Graham would be forced into a runoff on June 23.
Former President Donald Trump had endorsed Graham, even hosting a tele-rally on the eve of the election to boost voter turnout.
Trump celebrated Graham’s victory with a post on Truth Social on Tuesday night.
“Congratulations to Senator Lindsey Graham of the Great State of South Carolina on his BIG WIN tonight,” Trump wrote. “With almost 60% of the vote against a large field of very capable candidates, there will be no runoff.”
Graham was primarily challenged by businessman Mark Lynch, but Calvin Cowen, Thomas Dismukes, Pat Herrmann and Darius Mitchell also appeared on the ballot.
As the race was called, Graham was receiving around 58 percent of the vote to Lynch’s 27 percent, easily above the 50 percent threshold he would need to avoid the runoff.
Graham was aided by another challenger dropping out, former Heritage Foundation official Paul Dans, the architect of the controversial ‘Project 2025,’ who pulled out in April.

Trump cheered Dans’s exit, calling an endorsement from former Fox News talking head Tucker Carlson ‘THE KISS OF DEATH.’
Lynch also attracted the President’s ire.
Trump called Lynch a ‘LUNATIC’ and pointed out that he was supportive of Kentucky Representative Thomas Massie, who lost his primary to a Trump-backed candidate last month.
Lynch had applauded both Massie and former Representative Marjorie Taylor Greene, who left Congress after a high-profile spat with Trump over the Epstein files, among other things.
At the same time, Lynch was still complimentary of Trump during his run.
While campaigning, he took on Graham’s hawkish stance for the Iran war, especially as the conflict drags on and South Carolinians are paying the price at the gas pump.
He attracted the support of Dans, who posted to X on Election Day: ‘Today is Liberation Day South Carolina. Vote Mark Lynch and send Lady Graham off into the sunset.’
Trump’s first national security adviser, General Michael Flynn, also pushed to have Graham ousted.

Does Lindsey Graham’s win show South Carolina voters support his foreign policy, or just Trump’s backing?
‘Decades in Washington and what does South Carolina have to show for it?’ he asked, claiming that Graham supported ‘open borders’ and ‘endless foreign wars.’
Former Representative Ron Paul, the father of Kentucky’s libertarian-leaning Senator Rand Paul and a leader of the liberty movement while a member of Congress, echoed Flynn’s sentiment.
‘Will South Carolina finally reject the notorious warmonger in favor of a self-professed “real American first” businessman?’ the elder Paul asked in a social media post.
The Citadel Poll conducted in late May showed Lynch dragging Graham below the 50 percent threshold and thus triggering a potential runoff.
Pollsters only asked voters to choose between Graham and Lynch and found that 46 percent backed Graham and 36 percent supported Lynch.
This cycle, Democrats have coalesced around Dr Annie Andrews.
Andrews easily won her primary, with the AP making the race call at 8:31 pm ET.
Democrats bankrolled Graham’s last general election opponent, Jaime Harrison, who later became the Democratic National Committee chair, during the 2020 cycle.
Despite spending more than $130 million on the run, Harrison still fell short, losing to Graham six years ago 44 percent to the incumbent’s 54 percent.
South Carolina’s last Democratic senator was Fritz Hollings, who represented the state in the upper chamber from 1966 to 2005.
