Republican Representative Mike Collins won the Georgia Senate runoff on June 16, 2026, defeating Derek Dooley. Collins will face incumbent Senator Jon Ossoff (D-Ga.) in the general election scheduled for November 3, 2026. According to preliminary results from Georgia Secretary of State Brad Raffensperger's office, Collins secured approximately 55% of the vote. The Associated Press called the race for Collins shortly after 8:30 PM with 52% of the votes counted. Dooley conceded the race, acknowledging Collins' strong campaign.
Collins, who has been endorsed by former President Donald Trump, campaigned on a platform that emphasized immigration enforcement. He raised $4.3 million for his campaign, while Ossoff has raised over $57 million. The runoff is seen as a significant test of the Republican Party's direction in Georgia, with Collins representing the Trump-aligned faction. In his victory speech, Collins expressed gratitude to Dooley and Governor Brian Kemp, while Ossoff criticized Collins as an extremist on social media.
