Rep. Mike Collins Wins Georgia GOP Senate Runoff, Setting Up Matchup Against Sen. Jon Ossoff

Rep. Mike Collins has secured the Republican nomination for Georgia's U.S. Senate seat, defeating former college football coach Derek Dooley in a closely watched primary runoff. The Associated Press called the race on Tuesday evening, cementing a November matchup against incumbent Democratic Senator Jon Ossoff.[2][3]

The runoff victory followed a late intervention by President Donald Trump, who endorsed Collins just days before the election and after early voting had concluded. Trump praised the two-term congressman as a "true friend" and "warrior," helping push him past Dooley, who had the backing of term-limited Georgia Governor Brian Kemp.[3][7]

The Collins-Ossoff contest is expected to be one of the most expensive and consequential races of the 2026 midterm cycle. Ossoff is the only Democratic senator running for re-election in a state that Donald Trump won in the 2024 presidential election, making the seat a top target for Republicans aiming to secure control of the upper chamber.[2][5]

Collins, a 58-year-old trucking executive who has represented Georgia in the U.S. House since 2023, campaigned on a hardline conservative platform. He heavily emphasized border security and sponsored the Laken Riley Act, a 2025 law requiring the detention of immigrants accused of certain crimes, named after a Georgia nursing student killed in 2021.[2][3]

Dooley's supporters, including Governor Kemp, had argued that a political outsider would be more electable in a purple state like Georgia. However, Republican runoff voters ultimately favored Collins' established conservative record and his alignment with the "Freedom Caucus" wing of the party.[1][7]

The general election campaign began almost immediately with sharp attacks from both sides. In his victory speech, Collins cast Ossoff as an "out-of-touch far-left liberal" and predicted that national Democrats would work overtime to protect the incumbent.[3]

Ossoff's campaign quickly fired back, releasing a statement labeling Collins a "notorious bigot, antisemite, and extremist." The Democratic incumbent is seeking to tie Collins to Trump's trade policies, the Iran war, and recent tax legislation, while also highlighting an ongoing House Ethics Committee investigation into allegations that Collins misused congressional funds.[1][3][5]

Financial disparities will play a major role in the months ahead. Ossoff enters the general election with a massive fundraising advantage, having raised over $60 million through late April with $32.5 million in cash on hand. Collins, having just survived a competitive primary, reported having less than $1.2 million remaining at the end of May.[2][5]

The Senate primary was part of a broader split decision for Trump-endorsed candidates in Georgia. While Collins won his race, Republican voters rejected Trump's preferred candidate for governor, Lieutenant Governor Burt Jones, instead nominating billionaire healthcare executive Rick Jackson to face Democratic candidate Keisha Lance Bottoms.[1][2]

State Republican Chairman Josh McKoon expressed confidence that the party can unite its base and appeal to swing voters by framing themselves as the "party of common sense." Both parties are now preparing for a grueling five-month sprint in a state that has been decided by razor-thin margins in recent federal elections.[2][6]
