Oklahoma’s 1st Congressional District became an open seat after longtime Republican incumbent Kevin Hern launched a U.S. Senate bid in March 2026 following Markwayne Mullin’s appointment as Secretary of Homeland Security. The Tulsa-area district carries an R+11 partisan voting index and has delivered consistent Republican majorities in recent cycles, including Hern’s 60 percent share in 2024. A crowded Republican primary scheduled for June 16 features multiple candidates including state legislators and local officials, while Democrat John Croisant advanced unopposed after his party’s primary was canceled. Traders assign the Republican nominee an 87 percent implied probability of victory, reflecting the district’s structural advantage and limited recent polling shifts that would alter the expected outcome in November.
