Rep. Mike Collins (R-GA) won the Republican Senate runoff in Georgia on Tuesday, June 16, 2026 [1].
The victory secures the GOP nomination for the U.S. Senate seat and sets the stage for a high-stakes general election contest against Democratic Sen. Jon Ossoff.
Collins emerged victorious after a runoff was required because no candidate achieved a majority during the May primary [2]. The Republican candidate, who received the endorsement of former President Donald Trump, defeated former college-football coach Derek Dooley to secure the party's nomination [2].
The runoff took place on June 16, 2026 [1], concluding the intra-party battle for the seat. Collins now moves forward as the official Republican nominee for the 2026 election cycle [3].
The race will now shift toward the general election in November. This matchup pits Collins against Ossoff in a state that has become a central battleground for national political control. The contest is expected to draw significant attention as both parties vie for a critical seat in the U.S. Senate.
