Trump Backs Graham's Sister for South Carolina Senate Seat
Who will replace Graham as South Carolina Senator?
Polymarket prices this Darline Graham Nordone at 77%. The reporting broadly agrees.
Former President Donald Trump has publicly recommended Darline Graham Nordone, sister of the late Senator Lindsey Graham, to South Carolina Governor Henry McMaster as an interim replacement for the vacant U.S. Senate seat. Multiple outlets, including The Hill and Politico, reported Trump's endorsement, which came during a conversation with Governor McMaster. This recommendation positions Nordone as a leading contender for the appointment, with Crowdtells' market showing 77% probability that she will be the next person officially appointed to fill the seat. The governor's decision will determine who serves the remainder of Graham’s term, with the appointment expected to precede a special primary election.
Background
The sudden death of Senator Lindsey Graham has created a vacancy in South Carolina's U.S. Senate delegation, prompting Governor Henry McMaster to consider an interim appointment. Graham, a prominent Republican, had a long career in national politics, rising from his family's South Carolina cafe to become a close ally of former President Trump, particularly on national security policy. Under South Carolina law, the Governor has the authority to appoint a replacement U.S. Senator to serve until a special election can be held to fill the remainder of the term. The market resolves on November 2, 2026, if no appointment has been made before the midterm election.
The precedent
- In 2002, South Carolina Governor Jim Hodges appointed Jean Toal to fill a U.S. Senate vacancy created by the death of Senator Strom Thurmond, though she ultimately did not serve.
- Since 1945, there have been 19 instances of a U.S. Senator dying in office, leading to gubernatorial appointments to fill the vacancy.
