Jackson Lahmeyer is in the race for the Republican nomination in Oklahoma's First Congressional District, joining a field that now includes business owner Nathan Butterfield and state representative Mark Tedford. The 2026 primary is taking shape around an open seat, and Lahmeyer, a pastor, is one of the names Republican voters will be weighing.
The seat is open because Representative Kevin Hern is running for U.S. Senate, turning the First Congressional District into a contest with no incumbent on the ballot. That makes Lahmeyer's candidacy more than a routine filing; it places him in a three-way Republican field that will decide who carries the party into the general election.
For now, the basic answer to the question behind the race is simple: there are three Republicans running for the nomination, and Lahmeyer is one of them. The field is wide enough to keep the outcome unsettled, which is why the contest is drawing attention as the 2026 primary approaches. A prior report on Jackson Lahmeyer heads into runoff in House race is available here:
The pressure in this race comes from the open seat itself. Hern still holds the district, but his Senate bid leaves Republican voters choosing not just a nominee, but the person who may inherit a seat with no sitting member defending it. That usually gives a primary more room for surprises, and it leaves the party with a decision that could turn on name recognition, organization and turnout rather than incumbency.
What happens next is the Republican nomination fight in Oklahoma's First Congressional District Primary 2026. With Butterfield, Tedford and Lahmeyer in the mix, the immediate question is not whether there will be a contest, but which of the three can consolidate enough support to move on.
