Top Republican Says She’d Consider Graham’s Senate Seat

The political battle over one of the Republican Party’s most consequential Senate seats began taking shape almost immediately following the sudden death of South Carolina Sen. Lindsey Graham.

As state leaders prepared to address the vacancy and Republicans considered entering the race, Rep. Nancy Mace, R-S.C., publicly acknowledged that she would not rule out seeking Graham’s seat.

During a Sunday appearance on Fox News Live, Mace was asked directly whether she was considering a Senate campaign. While emphasizing that her immediate attention remained on Graham’s family and legacy, the congresswoman confirmed that the possibility was under consideration.

“I’m never going to shut the door,” Mace said.

“I love the state of South Carolina. You only live once, and you know, if the people of South Carolina would like me to serve in that capacity, I’ll certainly take a look at it. But right now, I just want to focus on him and his legacy.”

Mace’s remarks made her one of the first prominent South Carolina Republicans to openly signal interest in the seat following Graham’s unexpected death. She remains among several possible Republican contenders considering campaigns as the state prepares for an accelerated primary process.

Graham died on Saturday, July 11, at the age of 71 after returning to Washington from Ukraine, where he met with Ukrainian President Volodymyr Zelenskyy and continued advocating for stronger pressure against Russia.

His office initially described his death as the result of a “brief and sudden illness.” Preliminary findings later indicated that Graham suffered an aortic dissection associated with cardiovascular disease, although officials said final findings would require additional testing.

Graham’s death prompted an outpouring of tributes from Republican leaders, foreign officials, and former colleagues who remembered him as a relentless advocate for America’s military strength, national security, and global alliances.

President Donald Trump was among the first national leaders to publicly mourn the longtime senator and close political ally.

“Senator Lindsey Graham, one of the greatest people and Senators I have ever known, is dead!” Trump wrote on Truth Social.

“He was always working, and was a true American Patriot. Lindsey will be greatly missed!!!”

President Trump subsequently ordered American flags at the White House, federal buildings, military installations, and other government facilities to be flown at half-staff until 6 p.m. on July 18 in recognition of Graham’s service to the country.

Zelenskyy also paid tribute to Graham, who had remained one of Kyiv’s most vocal supporters in Congress.

“Deeply saddened by the news of the passing of United States Senator Lindsey Graham,” Zelenskyy wrote on X.

“Lindsey was a true defender of freedom and the values that make our world safer.”

During her Fox News interview, Mace disclosed that she had already discussed the vacancy with South Carolina Gov. Henry McMaster. She said she jokingly suggested that the governor appoint himself to serve temporarily in the Senate.

McMaster ultimately selected Graham’s sister, Darline Graham, to complete the remainder of her brother’s current term, which expires in January 2027. Her appointment made her the first woman to represent South Carolina in the United States Senate.

President Trump, who supported her appointment, has since encouraged Darline Graham to seek a full Senate term and offered her his endorsement should she enter the Republican primary.

That endorsement could significantly alter the calculations of Mace and other Republican officials considering campaigns, including Reps. Ralph Norman and Russell Fry, Lt. Gov. Pamela Evette, and businessman Mark Lynch.

The abbreviated Republican primary is scheduled for August 11, with a possible runoff on August 25. The eventual nominee is expected to face Democratic candidate Annie Andrews in the November general election.

Graham was first elected to the Senate in 2002 after serving four terms in the House of Representatives. During more than two decades in the upper chamber, he became one of Washington’s most recognizable Republican voices on military policy, national security, judicial confirmations, Israel, Iran, and America’s role overseas.

His political relationship with President Trump evolved considerably over the years. Although Graham was initially one of Trump’s Republican critics, he later became a dependable White House ally and played an important role in advancing the president’s judicial nominees and broader conservative agenda.

Graham’s death leaves South Carolina Republicans with the difficult task of choosing a successor capable of defending the state’s conservative values while navigating the high-profile national security and foreign-policy issues that defined much of his career.

Mace’s decision will now be closely watched. She possesses national name recognition and an established political operation, but she would likely face a crowded and fiercely competitive Republican field—particularly if Darline Graham accepts President Trump’s endorsement and formally enters the race.

What began as a period of mourning for one of South Carolina’s longest-serving senators is rapidly becoming one of the most closely watched Republican contests of the 2026 election cycle.
