Rep. Mike Collins has won the Republican runoff for Georgia's U.S. Senate seat, securing his party's nomination and advancing to a general election matchup against Democratic Sen. Jon Ossoff in one of the most closely watched races of the 2026 midterm cycle.
The two-candidate runoff was held after no Republican contender captured more than 50% of the vote in Georgia's May 19 primary election. Collins, a second-term congressman from Georgia's 10th Congressional District, defeated former college football coach Derek Dooley, who had entered the race with the backing of Georgia Gov. Brian Kemp.
