Congressman Kevin Hern won the Republican primary for the U.S. Senate seat in Oklahoma on Tuesday, a victory fueled by a last-minute endorsement from former President Donald Trump. The result cements the GOP’s hold on the deeply conservative state and clears a major hurdle for Hern ahead of the general election.
The Trump Factor
Trump threw his support behind Hern just days before the primary, giving the sitting congressman a powerful boost in a race that otherwise drew little national attention. The endorsement arrived via Trump’s social media platform, where he called Hern a “true patriot” and urged Oklahomans to vote for him. Hern, who has represented Oklahoma’s 1st Congressional District since 2018, has been a loyal ally of the former president, backing his 2024 campaign early and voting in line with Trump’s agenda on immigration and energy policy.
Political observers in the state said the endorsement likely tipped the scales. Hern’s primary opponents, who included a few lesser-known challengers, lacked the name recognition and fundraising that comes with Trump’s seal of approval. Turnout in the primary was moderate, but Hern’s margin of victory was decisive enough to avoid a runoff.
Solidifying GOP Dominance
Oklahoma hasn’t elected a Democrat to the U.S. Senate since 1990, and Tuesday’s result does nothing to change that streak. Hern will face Democratic nominee Madison Horn in November, but the district is rated solidly Republican by nonpartisan analysts. Horn, a cybersecurity executive, has run a low-budget campaign and faces an uphill battle in a state where Trump won by more than 33 points in 2020.
Hern’s win also signals that Trump’s influence in primary races remains potent, even as he faces multiple criminal indictments and a crowded field of Republican presidential contenders. The former president has endorsed dozens of candidates this cycle, with mixed results nationally, but in Oklahoma his backing still carries weight.
What Comes Next
The general election is Nov. 5. Hern is expected to campaign on economic issues — he chairs the Republican Study Committee, a group of conservative House members — and on his record of opposing abortion and supporting gun rights. Horn will likely highlight her background in cybersecurity and criticize Hern for voting against certifying the 2020 election results.
Hern’s campaign didn’t release any immediate statement after the race was called. The Oklahoma State Election Board will certify the results in the coming days.
