Trump-Backed Rep. Mike Collins Wins Georgia GOP Senate Runoff
Rep. Mike Collins won the Republican Senate runoff in Georgia on Tuesday, June 16, 2026, securing the GOP nomination to challenge Democratic Sen. Jon Ossoff in November.[1]
The Associated Press called the race for Collins as returns became clear Tuesday evening.[2] President Donald Trump endorsed Collins shortly after early voting ended, posting his support in the early hours of Sunday, June 14, 2026, and criticizing Derek Dooley's Georgia ties and voting record.[2] Dooley was backed by term-limited Gov. Brian Kemp and First Lady Marty Kemp, and Kemp's top political adviser served as a senior consultant to Dooley's campaign.[3]
In the May 19 Republican primary, no candidate won a majority, forcing the June 16 head-to-head runoff between Collins and Dooley.[1] Collins built his campaign around support for Trump's agenda, border security, immigration enforcement and conservative cultural issues.[4] Some Republicans flagged his hardline abortion stance, social media posts that downplayed the January 6 attack and an Office of Congressional Conduct probe as potential general-election vulnerabilities.[4]
The result sets up a high-stakes November matchup in Georgia, a state Trump carried in 2024 and where Democrats have defended tight Senate races.[1] Both parties are expected to pour resources into the race, with Democrats defending Sen. Jon Ossoff and Republicans viewing the seat as a key pickup opportunity.[5]
The mainstream summary does not mention the low turnout in the June 16 runoff, which was approximately 6.6% of the voting population, a stark contrast to the roughly 28% turnout in the May primary. This significant drop in voter engagement could impact the dynamics of the upcoming general election against Sen. Jon Ossoff, who is currently leading Collins in recent polls by margins of 4 to 7 points. These factors suggest that Collins may face considerable challenges in November, despite his victory in the runoff.[6]
Additionally, the mainstream account downplays the intra-party tensions highlighted by Collins' win over the establishment-backed Dooley, particularly in the context of ongoing factionalism within the Republican Party. The Collins-Dooley race reflects a broader struggle between Trump loyalists and traditional GOP figures, a divide that has roots in the 2020 election disputes involving Gov. Brian Kemp. This backdrop adds complexity to Collins' candidacy as he prepares for a highly competitive general election.[7]
