Story Highlights
- President Donald Trump endorsed Representative Mike Collins in Georgia’s Republican Senate runoff against Derek Dooley.
- Collins led the May primary and has built his campaign around immigration enforcement, conservative policy and support for Trump’s agenda.
- The June 16 winner will face Democratic Senator Jon Ossoff in one of the country’s most competitive Senate elections.
What Happened
President Donald Trump endorsed Representative Mike Collins in Georgia’s Republican Senate runoff, giving the congressman a major advantage shortly before voters select the party’s nominee.
Trump announced his support on Truth Social, praising Collins as a reliable conservative who had supported the president and the Make America Great Again movement.
The endorsement came two days before Collins faces former college football coach Derek Dooley in the June 16 runoff.
- Collins finished first in the May 19 Republican primary with approximately 41 percent of the vote.
- Dooley advanced after narrowly defeating Representative Buddy Carter for second place.
- No candidate received the majority required to avoid a runoff.
Collins represents Georgia’s 10th Congressional District and previously operated a trucking business.
He has emphasized border security, law enforcement, lower taxes and support for Trump’s broader domestic agenda throughout the Senate campaign.
Collins also introduced the House version of the Laken Riley Act, which expanded federal detention requirements for certain undocumented immigrants accused of specified crimes.
The legislation passed Congress with support from Republicans and a group of Democrats before Trump signed it into law.
Dooley has campaigned as a political outsider with experience in leadership and management rather than elected office.
He is backed by Georgia Governor Brian Kemp, whose political organization recruited and supported him as a candidate believed capable of appealing to suburban and independent voters.
Why It Matters
Georgia is expected to be one of the most closely watched Senate races of the 2026 midterm elections.
Democratic Senator Jon Ossoff is seeking reelection in a state Trump carried in 2024, giving Republicans a realistic opportunity to gain a Senate seat.
Trump’s endorsement could be especially influential in a low-turnout Republican runoff where the most committed conservative voters are likely to decide the outcome.
- Collins already entered the runoff as the first-place primary finisher.
- Trump’s support may help consolidate voters who previously backed Buddy Carter.
- The endorsement gives Collins additional national attention and fundraising opportunities.
The decision also shows that Trump is prioritizing a candidate with a record directly connected to his immigration and border-security platform.
Collins can point to the Laken Riley Act as evidence that he has converted conservative campaign priorities into federal legislation.
That record may allow Republicans to present him as more than a candidate relying only on political loyalty.
The neutral concern is whether Collins’s strongly partisan style will appeal to the suburban voters who often determine statewide elections in Georgia.
Dooley and Kemp argue that a candidate with a less confrontational image may be better positioned against Ossoff in November.
Political and Public Context
The runoff reflects two competing approaches to Republican politics in Georgia.
Trump is backing an experienced congressman closely associated with the MAGA movement, while Kemp supports a first-time candidate presented as a conservative outsider.
The difference is partly about political style, but both campaigns broadly support lower taxes, stronger border enforcement and Republican control of the Senate.
- Trump’s endorsement emphasizes party loyalty and a proven conservative record.
- Kemp’s support emphasizes statewide electability and suburban appeal.
- Georgia Republican voters will decide which approach offers the stronger general-election campaign.
Trump and Kemp have had a complicated relationship since the disputed aftermath of the 2020 presidential election.
However, the runoff should not be viewed only as another personal confrontation between them.
Both men want Republicans to defeat Ossoff, and the eventual nominee will likely need support from both the Trump and Kemp wings of the party.
The endorsement gives Trump another opportunity to demonstrate his influence over Republican primary voters after several of his preferred candidates won significant contests earlier in the election cycle.
A Collins victory would strengthen the argument that Trump remains the party’s most important endorsement source.
A Dooley victory would show that Kemp’s organization and electability message continue to carry substantial influence in Georgia.
What Happens Next
Georgia Republicans will vote in the runoff on June 16.
Early voting has already accounted for a substantial portion of the expected turnout, meaning Trump’s late endorsement may have its greatest effect on voters casting ballots on Election Day.
The winner will immediately begin preparing for a costly and nationally significant campaign against Ossoff.
- Watch whether Trump’s endorsement increases Election Day turnout for Collins.
- Monitor where former Buddy Carter supporters move in the runoff.
- Follow whether Kemp fully supports the Republican nominee after the vote.
- Track national party spending once the general-election matchup is established.
Ossoff is expected to emphasize healthcare, abortion rights, government ethics and the effect of Trump administration policies on Georgia families.
The Republican nominee will likely focus on immigration, inflation, public safety and Ossoff’s support for the Democratic agenda.
Collins would enter the general election with Trump’s enthusiastic support and a clear legislative record on immigration.
Dooley would argue that his outsider status and connection to Kemp offer Republicans a broader coalition.
For Trump, endorsing Collins gives voters a direct choice between a candidate who has worked with his administration and one supported by Georgia’s Republican establishment.
The runoff result will show whether Georgia Republicans believe a strongly Trump-aligned nominee offers the best path to defeating Ossoff and expanding the party’s Senate majority.
