Darline Graham won the South Carolina Republican primary runoff for a U.S. Senate seat on Tuesday night.

The result confirms the continuing influence of former President Donald Trump over the Republican nominating process in a key Southern state.

Graham defeated Rep. Ralph Norman to secure the nomination. Her victory is attributed to an endorsement from Donald Trump, higher Republican voter turnout, and significant financial support from Trump-aligned political action committees.

Financial records indicate that ad spending in the runoff amounted to millions of dollars [1]. These funds were deployed through PACs to boost Graham's profile and challenge Norman's candidacy in the final stage of the primary process.

While some early reports projected a win for Graham, subsequent updates confirmed her victory in the race. The runoff served as the final hurdle in the GOP's internal competition for the seat.

Graham's campaign focused on aligning with the national party platform and leveraging the support of the former president to mobilize the base. The high turnout among Republican voters helped solidify her lead over Norman during the Tuesday night vote.
