Mike Collins toppled Brian Kemp's handpicked candidate Tuesday to claim the Georgia GOP Senate nomination, setting up a fall showdown with a vulnerable Democratic incumbent Jon Ossoff.
Trump's endorsement just beat Kemp's machine. That is the short version of what happened in Georgia's Republican Senate runoff Tuesday, when U.S. Rep. Mike Collins defeated Derek Dooley, a former college football coach backed by the state's term-limited governor, to earn the GOP nomination against Democratic Sen. Jon Ossoff this November. NBC News and CBS News projected Collins the winner.
It was a direct test, and Trump passed it. Kemp is popular in Georgia, having won re-election by nearly eight points in 2022 even as Trump worked to defeat him, and he had been squarely in Dooley's corner. Collins, a congressman first elected in 2022, had the president's endorsement, delivered just three days before the vote on June 14, and made no apologies for it. "Conservative workhorse" was his shorthand for himself on the trail. Georgia Republican primary voters chose it.
Collins did not leave his general-election message for later. Ossoff, he has said plainly, "doesn't represent us, he doesn't reflect our state and represent the people or our values." That is not a subtle frame. It is the argument that will define the next five months.
Kemp versus Trump has been a slow-burn subplot of Georgia Republican politics since 2021, when the governor refused to overturn certified presidential results and the former president never forgave him. Backing Dooley was, among other things, a chance to deny Trump another scalp in his own state.
He did not get that chance.
That does not finish Kemp as a figure in Georgia politics. A governor with a high approval rating and a strong governing record still carries weight. But what Tuesday demonstrated is that when Trump personally enters a contested Republican runoff seventy-two hours before the polls open, the base still moves. That is useful intelligence heading into a midterm cycle where Trump's coattail strength will be tested across a half-dozen competitive states.
Collins now has to decide how to wear those coattails into a general election that Ossoff will not simply concede. Georgia is a genuine swing state. Trump carried it in 2024, but narrowly, and Ossoff has held his seat since January 2021. The runway from winning a Republican runoff to flipping a Senate seat is not short.
Ossoff's Numbers Give Collins an Opening
National forecasters rate the Georgia Senate race a dead heat, and the polling backs that up. Ossoff enters the general with roughly 47 percent approval, according to Emerson College polling. He leads generic Republican matchups in some surveys. He is not walking into November as a sure loser.
But the internals are worse than the top line. A recent Atlanta Journal-Constitution poll found only 36 percent of Georgia voters believe Ossoff deserves re-election. Forty-nine percent say it is time for a change. Nearly two-thirds of Republicans disapprove of his performance. Independents, who will decide this race, are disillusioned with the incumbent without yet being sold on the Republican alternative, according to Atlanta News First's September 2025 survey, which also found Ossoff polling most weakly on immigration and crime.
Those two issues are exactly where Collins will press. He has run hard on the Trump agenda in the House and will not let border security or public safety fade quietly into the background. Ossoff will counter by running on constituent services, bipartisan credentials, and whatever distance he can credibly claim from an unpopular national Democratic brand. Neither strategy is obvious folly.
The case Kemp's allies made for Dooley was that a candidate with crossover appeal, a recognized name in Georgia football culture, and enough separation from Washington gridlock might have an easier path through the suburbs. There is something to the theory. It did not win the day, and Collins is now the one who has to thread that needle.
Georgia handed two Democrats Senate seats in January 2021 and gave Trump its electoral votes in November 2024. It does not belong to either party, and Senate control could turn on it. Republican strategists who had the seat circled as a top pickup before the runoff have not changed their assessment. Collins will need to hold the base Collins just consolidated while peeling off enough independents and soft Ossoff supporters to get over the line. The runoff is settled. The real race begins now.
