Darline Graham Nordone, chosen to fulfill the remainder of her brother Lindsey Graham's Senate term after his death, faces Representative Ralph Norman in a runoff to secure the Republican nomination for the special election. Former President Donald Trump endorsed Nordone shortly after she was selected.
The endorsement gave Nordone a significant advantage in a primary field that included multiple candidates.
The runoff will determine the Republican nominee for the Senate seat, which will be contested in the general election in November.
Market odds currently place the likelihood of Nordone winning the runoff at 70.35%, reflecting the Trump endorsement and her status as the appointed incumbent.
The next milestone is the runoff, which will decide the nominee.
