Oklahoma's 1st Congressional District, an open seat after incumbent Kevin Hern's March announcement to pursue a U.S. Senate bid, features a Cook Partisan Voter Index of R+11 and ratings as Solid Republican by Cook Political Report. Candidate filings closed April 3 with 11 Republicans—led in fundraising by Mark Tedford—crowding the June 16 primary, while Democrat John Croisant advances unopposed after his primary cancellation. Recent polling shows Tedford ahead in the GOP contest, but trader consensus at 86.5% for Republican Party reflects the district's history of 60%+ GOP general election margins since 2020 and minimal Democratic opposition, with the primary winner favored for November 3 amid low competitiveness.
