Trump Endorsement Vaults Graham’s Sister to Front-Runner in South Carolina Primary
Trump backs Darline Graham Nordone to fill her late brother Lindsey Graham's Senate seat, and prediction markets now give her an 80% chance to win the special Republican primary.
WASHINGTON D.C. — Donald J. Trump has turned Darline Graham Nordone into the clear favorite to fill her late brother Lindsey Graham’s Senate seat, a CNN data analyst said.
Nordone’s odds of winning South Carolina’s special Republican primary jumped to 80% from 14% within days of Trump’s endorsement, according to Kalshi prediction markets cited by mediaite. Lindsey Graham, the four-term senator from South Carolina, died suddenly on July 11.
“Darline Graham’s chances have rocketed up because rarely has the power of one man and his endorsements in primaries been as strong as with Trump,” said Harry Enten, senior data reporter at CNN, in an on-air analysis.
The surge underscores how a single Trump endorsement can reset a race overnight, a dynamic that shapes control of the Senate and the balance of power in Washington.

This is Trump’s 16th message released today. On average, Trump produces 18 posts per day since his inauguration on January 20, 2025.
The move fits a broader pattern in Trump’s recent messaging, with 74 of his 482 posts over the last 30 days focused on elections.
Trump was the first to suggest Nordone take over her older brother’s seat after his death, calling it “a fabulous tribute to Lindsey!” by mentioning the source (see mediaite). Nordone has since said she will run for a full six-year term. The endorsement moved her from long-shot status to front-runner in a matter of days.
The stakes reach well past one seat. A Republican hold in South Carolina protects the party’s Senate math, while Nordone’s path shows how loyalty to Trump has become the decisive currency in Republican primaries. Rival candidates who lack that backing face steep odds, and donors and party operators read an endorsement as a signal to fall in line.
Trump’s primary record explains the sharp market swing. Trump-endorsed candidates have won Senate primaries as non-elected incumbents about 95% of the time since 2022 and 100% of the time this year, according to mediaite. That track record, Enten said, drove prediction markets and conventional wisdom to move rapidly once the endorsement landed.
For the average reader, the contest determines who casts votes on taxes, spending and judicial confirmations for the next six years. A senator’s decisions ripple into household budgets and federal policy, making a single primary a national concern rather than a local one.
This has happened before. Trump-backed candidates in open Senate races have repeatedly overtaken better-funded or better-known rivals after his endorsement, a pattern Enten described as unmatched in modern primary politics.
South Carolina voters will render the next decision at the special Republican primary. A date for that primary has not been announced.
Family succession to a Senate seat is an old thread in American politics. Allies of Huey Long, the Louisiana senator and former governor, engineered his widow Rose McConnell Long into the seat after his 1935 assassination, and she served briefly before stepping aside. Lurleen Wallace won the Alabama governorship in 1966 as a stand-in for her term-limited husband George. Such handoffs have long depended on a powerful patron, and the patron’s name, not the successor’s, usually decided the outcome.
