Sen. Lindsey Graham, the South Carolina Republican who chaired the Senate Budget Committee and spent years pushing Trump toward war with Iran, died Saturday night, July 11, at 71 from an aortic tear. He'd just won the June 9 Republican primary with 56.8% of the vote and was running for a fifth term in November. By Monday, Gov. Henry McMaster had appointed Darline Graham Nordone — Lindsey's sister, 62, and South Carolina's first female senator — to serve out the remaining months of his term. She's never held elected office; since 2019 she's run the state Commission for the Blind. State law requires a special Republican primary on August 11 to pick the Republican nominee for November. The filing window opens July 21. The Democratic nominee is Annie Andrews, a pediatrician.

1. Appoint the Sister, Stabilize the Seat (Trump, Gov. Henry McMaster)

Trump recommended Darline Graham and McMaster went along: stability now beats a primary fight.

The appointment came fast and Trump backed it on social media. McMaster named Darline Graham Nordone within 48 hours of Graham's death. Darline and Lindsey grew up together in Central, South Carolina. Their parents both died within 15 months of each other, leaving Lindsey — then in college — to become her legal guardian when she was 13.

Picking a candidate for the full term can wait. On "Meet the Press" Sunday, Trump said he has someone in mind but refused to name who: "I'm not going to tell you who now because it's too soon." He praised McMaster warmly in the same interview, which suggested he approves of the caretaker appointment.

Republicans need the seat to stay stable through November. They hold a 53-47 edge in the Senate. Graham was Budget Committee chair. His vote mattered on the Iran war defense spending package, the Blanche AG confirmation, and conservative judicial appointments. A chaotic primary fight right now would be a distraction from all of it.

2. But South Carolina Republicans Should Decide (Rep. Nancy Mace, Rep. Ralph Norman)

South Carolina voters should choose their senator in a primary, not inherit a political unknown.

The appointment went to the wrong person. Rep. Nancy Mace told CNN that McMaster should have appointed himself. Naming a sitting House member would shrink the slim Republican House majority. Appointing McMaster himself would keep the House intact and give the interim seat real political weight. Darline Graham Nordone has never run for office. Washington Post reported she has "little political history beyond praising her brother."

The August 11 primary already has a field forming. Mace is running internal polls this week to gauge whether a run is viable. Rep. Ralph Norman is also weighing a run. Mark Lynch — who came in at 43% against Graham in the June primary — has announced he's running and pledged $5 million to his effort.

Filing opens July 21, giving candidates less than a week to declare. Mace finished fifth against Graham in a 2014 Senate primary and fifth again in this year's gubernatorial race. She thinks the South Carolina Republican electorate has shifted enough to give her a different result.

Where This Lands

Graham was one of the Senate's most consequential foreign policy voices. He advised Trump on Iran and Ukraine, and Fortune's obituary noted his pressure on the president "is thought to have played a part in persuading the President to go to war." Israeli Prime Minister Benjamin Netanyahu called him "a great friend of Israel and a cherished friend of mine," and Graham traveled to Ukraine 10 times to meet with Zelenskyy. Darline Graham Nordone holds the seat through January, but she's the caretaker, not the policymaker. Whoever wins the August 11 primary goes on the November ballot and inherits one of the Senate's most powerful foreign policy posts. Trump and McMaster are betting a caretaker appointment is the right call. Mace and the emerging field think South Carolina voters should decide.
