OKLAHOMA CITY — Oklahoma’s 2026 election season came into sharp focus last week as the candidate filing period closed, revealing a mix of crowded primaries, uncontested races and a handful of races that will carry through to November.
U. S. Senate At the top of the ballot, Oklahoma’s lone U.S. Senate race is wide open and will be one of the most competitive in the state. With the appointment of Markwayne Mullen to head up the department of Homeland Security, there is no incumbent in the race.
Five Republicans, Kevin Hern, Sean Buckner, Brian Ragain, Nick Hankins and Gary Ty England, filed for the seat, while Troy W. Green, Jim Priest, R.O. Joe Cassity Jr., N’Kiyla Jasmine Thomas and Ervin Stone Yen entered the race as Democrats. Libertarian Sevier White and independents Curtis Stinnett and Ron Meinhardt round out the field.
With multiple candidates on both sides, all parties will hold primaries, and the race will likely be decided in the November general election.
U. S. House In the U.S. House, Oklahoma’s 3rd Congressional District features longtime incumbent Frank Lucas, who was first elected in a 1994 special election and has now served more than three decades in Congress. Lucas faces a Republican primary challenger in Wade Burleson, while Democrats Jules Roberson and Suzie Byrd will compete for their party’s nomination.
The District 3 race will require primaries on both sides before advancing to a general election.
In the 5th Congressional District, incumbent Stephanie Bice, first elected in 2020, is seeking another term. She faces no opposition in the Republican primary, effectively securing her party’s nomination. On the Democratic side, Jena Nelson and Trey Martin will face off in a primary, while independents Robert P. Henri and Austin Nieves have also filed, ensuring a multicandidate general election in November.
Oklahoma Senate In State Senate District 8, incumbent Bryan Logan, who was elected in a 2025 special election, filed for another term and will face Nathan Brewer, a Democrat. With one Republican and one Democrat in the field, there is no primary contest to settle the seat; that race goes straight to the November general election. Logan’s official Senate page says he was elected in 2025, and the filing book confirms the two-candidate field.
In State Senate District 12, incumbent Todd Gollihare is seeking another term. Gollihare, whose official Senate materials show he began his first term in 2022, drew a Republican challenger, Wm Craig Stump, while Erica Watkins filed as a Democrat. That means Republicans will have to sort out their nominee in the June 16 primary, and the seat will then be decided in the November general election.
In State Senate District 20, incumbent Chuck Hall, first elected in 2018, filed for reelection and drew a Republican challenger in Mark LeMarr. No Democrat, Libertarian or independent filed for the seat. Unless the field changes during the withdrawal window, that makes Senate District 20 a classic case where the Republican primary will effectively decide the race. Hall’s official Senate page confirms he has served since 2018.
State Senate District 21 is not on the ballot this year. The official filing book does not list the district among 2026 Senate races, and the current senator remains Randy Grellner, whose official Senate page says he has served since 2024. So for SD 21, there were no candidates filing last week because there was no election for that seat this cycle.
Oklahoma House On the House side, District 29 features incumbent Kyle Hilbert against Brian Jackson, both Republicans. The filing book shows no Democrat or independent in the race, so the June primary will decide the seat. Hilbert is the current representative and House speaker; multiple House sources identify him as the current member, and secondary legislative references show he was first elected in 2016.
In House District 30, incumbent Mark Lawson filed for reelection and will face Democrat Sonya Amling. Because there is only one Republican and one Democrat in the race, neither side needs a primary here, and the contest goes directly to the November general election. Lawson’s official House biography says he has served District 30 since 2016.
House District 35 is another race likely to be settled in June. Incumbent Dillon Travis, who was elected in the Feb. 10, 2026 special election and sworn in later that month, filed for reelection and will face Kevin Wright in the Republican primary. No Democrat or independent filed, so the Republican winner would take the seat.
In House District 36, incumbent John George filed for reelection and drew two Republican challengers, Jenni White and Joe Sarge Nelson. Democrat Leslie Hellebuyck also filed. That means House District 36 will have a contested Republican primary followed by a November general election. George’s official House biography says he was elected in 2022.
And in House District 39, incumbent Erick Harris filed for reelection and drew a Republican challenger, Ronda Peterson. No Democrat or independent appears in the filing book for the district, which means the Republican primary is positioned to decide the seat. Harris won a special general election in February 2024 and was sworn in later that month.
Taken together, the state-level filing picture is straightforward. Senate District 8 and House District 30 go straight to November. Senate District 12 and House District 36 require a primary and then a general election. Senate District 20, House District 29, House District 35 and House District 39 are currently set to be decided in Republican primaries because no other party filed. And Senate District 21 is simply not on the ballot in 2026.
That leaves June 16 as the real battleground in several of these districts, especially where one-party dominance means the primary winner is effectively the next officeholder. For the others, the candidate filing period merely set the stage for November.
