Rep. Mike Collins won Georgia’s Republican Senate primary runoff Tuesday, defeating former University of Tennessee football coach Derek Dooley.
Now, he will have the far larger task of knocking off Democratic Sen. Jon Ossoff in one of the most competitive Senate race this election cycle.
The runoff was triggered after Collins and Dooley each failed to win a majority in the May 19 primary, forcing a second round in a contest that Republicans view as one of their best opportunities to flip a Democratic-held Senate seat in 2026. President Donald Trump endorsed Collins over the weekend, boosting his chances in the runoff.
Collins, a congressman representing Georgia’s 10th District, finished first in the primary. The trucking company owner and staunch ally of Trump built his campaign around support for the president’s agenda, border security, immigration enforcement and conservative cultural issues. Collins sought to portray himself as a proven conservative fighter with experience in Washington and strong ties to the Republican base.
Dooley, meanwhile, leaned on his name recognition as a former college football coach and member of one of Georgia’s most prominent political families. His father, Vince Dooley, was the legendary University of Georgia football coach and athletic director. Although Dooley has never held elected office, he has campaigned as a political outsider capable of attracting independent and swing voters in a general election.
Collins argued that Republicans need a candidate with a proven conservative record and close ties to Trump. Dooley has countered that his outsider status and broader appeal would make him a stronger challenger in November.
But some Republicans are worried about Collins, including his hardline stance on abortion rights and an Office of Congressional Conduct probe into his office’s potential misuse of resources that the Republican lawmaker has referred to as a “nothing burger.”
