Graham Wins South Carolina Republican Senate Primary, Defeating Challengers
The victory came amid a crowded field that included Greenville businessman Mark Lynch and former state representative Thomas Dismukes. President Donald Trump, who had endorsed Graham, took to social media to rally support, calling Lynch a “lunatic” and a “disaster for the Republican Party.” Trump’s endorsement, coupled with the president’s criticism of Lynch, helped cement Graham’s appeal among South Carolina’s conservative base, who see his long tenure as a marker of experience and stability.
Lynch campaigned on a platform that attacked Graham’s foreign‑policy record, labeling him a “warmonger” for supporting Israel and for military action against Iran. Lynch drew support from figures critical of Israel, including former Rep. Marjorie Taylor Greene and Rep. Thomas Massie, both of whom have publicly accused Israel of committing “genocide” in Gaza.
Other challengers included former state representative Thomas Dismukes and Paul Dans, a former Trump administration official and Project 2025 architect. Dans withdrew his candidacy in April and endorsed Lynch. He had previously received backing from conservative commentator Tucker Carlson, who has been outspoken about U.S. policy toward Israel.
Graham has long been one of the Senate’s most vocal supporters of Israel’s right to defend itself against Hamas, Hezbollah, and Iranian‑backed terrorist groups. He has repeatedly argued that a strong U.S. commitment to Israel is essential to American national security and stability in the Middle East. His primary win suggests that many South Carolina Republicans continue to back that message despite growing isolationist sentiment in parts of the party.
The primary results also reflected a record turnout during South Carolina’s early‑voting period, with more than 319,000 ballots cast in the state’s Democratic and Republican primaries. The high turnout underscored the importance of the Senate race in a state that has consistently leaned Republican in recent decades.
Graham will face Democratic nominee Annie Andrews, a pediatrician who won the state’s Democratic primary, in the November 3, 2026 general election. Political analysts view South Carolina as a strongly Republican territory, and Graham enters the general election as the heavy favorite.
The outcome preserves one of the Senate’s most influential pro‑Israel voices and sets the stage for a general‑election contest that will test the state’s partisan alignment. As the campaign season moves forward, both parties will focus on voter outreach and messaging, while the Senate race remains a key indicator of broader electoral trends in the South.
