Our verdict

LiberalMind endorses Mark Tedford — as unproven in Congress, and on watch

Election Day is Tuesday, November 3, 2026, and voting is already underway in Oklahoma. This is the whole race — the records, the claims against each candidate, and what the sources actually show.

The setup

Oklahoma's 1st District — Tulsa — is an open seat. Rep. Kevin Hern (R), first elected in 2018 and re-elected with 60.4% in 2024, announced on March 11, 2026 that he would run for the U.S. Senate seat vacated by Markwayne Mullin, and won the Republican Senate nomination on June 16 (Wikipedia; Tulsa Flyer; Cook Political Report — "OPEN, Kevin Hern (R), Running for Senate"). One wording conflict, printed rather than buried: a Tulsa Flyer voter guide says Hern "resigned to run for the Senate," while other sources describe a sitting incumbent running for Senate — the open-seat fact is agreed by every source; the resignation wording is corroborated by none of the others. Cook PVI is R+11 and Cook rates the race Solid R. Two names are on the ballot — no Libertarian or independent filed (BatesLine, June 2026).

How the Republican nominee was set matters here: Mark Tedford led the June 16 primary with 32.2% to Jackson Lahmeyer's 25.9%; Lahmeyer withdrew from the August runoff the next day, making Tedford the nominee, and President Trump switched his endorsement from Lahmeyer to Tedford (Oklahoma Voice / KCN, June 18, 2026; The Oklahoman, Oct. 25, 2026).

Mark Tedford (Republican)

The record: Tedford is a state representative for Oklahoma House District 69 — south Tulsa, Jenks, parts of Bixby — elected to the state House in 2022 (Tulsa Flyer; The Oklahoman). He has worked in the insurance industry since 1992 and is described by the U.S. Chamber as an insurance business owner. His reported campaign priorities: lowering costs, protecting Social Security, cutting taxes, and federal-spending oversight (The Oklahoman, Oct. 25, 2026). He is endorsed by President Trump and the U.S. Chamber of Commerce.

Pros: Four years of state legislative service, three decades in a real business, and the district's own Republican voters' plurality ratified by his runoff opponent's withdrawal — the primary effectively settled twice. Cons: A 32.2% primary plurality is a plurality, not a mandate, and his record is state-level and short. The flaw, plainly: unproven at the federal level — a watch-closely posture, not a demerit.

John Croisant (Democratic)

The record: Croisant has sat on the Tulsa Public Schools board since July 2020; he is a former teacher and coach — 16 years teaching, per The Oklahoman — and owns an Allstate insurance agency, a business owner for the past eight years (Tulsa Flyer; The Oklahoman). On the board he opposed a state takeover effort under former Superintendent Ryan Walters and campaigned for voter-approved bond packages in 2021 and 2026 (Tulsa Flyer). His reported priorities: healthcare expansion, public-education investment, childcare affordability, and Social Security protection (Tulsa Flyer).

Pros: A mirror-image biography — educator and insurance owner against legislator and insurance owner — with six years of elected school-board service in the district's biggest city. Cons: The service he has is school-board service spent fighting the state's conservative education administration, and his stated program is his party's: healthcare expansion and education spending with no documented break toward our values. The flaw, plainly: a real local record whose documented direction runs against the values this publication applies; the exception is earned by breaks toward them.

OUR CALL

LiberalMind endorses Mark Tedford — as unproven in Congress, and on watch.

An open R+11 seat: the Republican is a sitting state legislator with the president's endorsement; the Democrat is a school-board member whose documented fights are against the state's conservative education leadership. The call goes to the aligned candidate, and the watch goes with it.
