A Republican Senate primary runoff has resulted in a victory for Sen. Darline Graham. She defeated Rep. Ralph Norman, with nearly all of the vote tallied, leading roughly 52% to 48%. This outcome is seen as a win for President Donald Trump, who supported Graham's campaign.

Graham's campaign followed the death of her brother Lindsey Graham six weeks prior. President Trump had recruited, endorsed, and campaigned for her.

Further details about the election and its aftermath are available from the source, including Sen. Graham's remarks to her supporters on election night.
