Live results: Trump seeks primary win in Oklahoma governor's runoff

Sen. Darline Graham, endorsed by President Trump, secured the Republican nomination for the South Carolina Senate seat vacated by her brother Lindsey Graham's death, according to the Associated Press. This victory highlights Trump's ongoing influence among Republican voters and positions Graham as the frontrunner in the November general election. At 62, Graham is heavily favored to win against Democrat Annie Andrews, who has not won a U.S. Senate race in South Carolina since 1998.

Graham and Rep. Ralph Norman, both Republicans, emerged as the top two finishers in the August 11 primary and advanced to the runoff after neither achieved a majority. Graham entered the race on July 20, just days after her appointment to temporarily fill her late brother's Senate seat, marking her first elected office experience.

Her campaign gained momentum due to Trump's endorsement, her incumbency, and recognition as a prominent South Carolina figure. MAGA Inc. also contributed significantly to her campaign, investing over $827,000 in phone calls and texts ahead of the runoff, as reported by the Federal Election Commission.

During the runoff debate, Graham's admission of limited knowledge on national security, particularly regarding U.S. policy toward Taiwan, raised questions about her qualifications for the role. This comment contrasted sharply with her late brother Lindsey, who had a longstanding reputation as a Senate leader on foreign policy and national security.

Rep. Ralph Norman, 73, criticized Graham's response, stating that voters should evaluate candidates based on their records, positioning himself as a consistent conservative rather than a first-time candidate propelled by a renowned name.

Both candidates heavily invested in advertising, spending over $5 million on ads during the primary runoff, according to AdImpact. Pro-Graham advertisements emphasized supporting President Trump, while Norman's ads portrayed him as a seasoned conservative with a track record of fighting for constituents' interests. The election's outcome is seen as non-negotiable, with Norman asserting that South Carolina needs a proven conservative senator with a proven track record.
