President Trump helped political novice Darline Graham win the South Carolina Senate primary runoff despite her lack of experience. His PAC spent over $800,000 supporting her campaign. Graham, who had no prior political background, defeated her opponent to succeed her late brother, Senator Lindsey Graham.

The victory demonstrated Trump’s continued influence over the Republican base, even as his approval ratings have declined. Meanwhile, another Trump-backed candidate, Mike Mazzei, won the Oklahoma governor’s primary runoff. Graham’s win came at a cost, as Trump invested significant time and resources in a race unlikely to affect congressional control.

Still, South Carolina voters showed strong loyalty to Trump, with many citing his endorsement as decisive. Graham thanked Trump at her election night event, calling the state “Trump country.” Her victory reinforced Trump’s ability to shape primary outcomes, even as the party looks toward a post-Trump future.
