Republican Mark Tedford Wins Oklahoma House District 1 Seat
Republican Mark Tedford defeated Democrat John Croisant to win the U.S. House District 1 seat in Oklahoma during the November 3 general election.
Mark Tedford won the election for Oklahoma's District 1 U.S. Representative on Tuesday, November 3, 2026, defeating Democratic candidate John Croisant. The Associated Press projected Tedford as the winner of the race for the seat, which became open after incumbent Kevin Hern opted to run for the U.S. Senate.
Tedford, a member of the Oklahoma State House representing District 69 since 2022 with a background in insurance, campaigned on a platform of strict immigration enforcement, increased domestic energy production, and fewer business regulations. He emphasized an America-first economy during his bid for the district, which encompasses four counties in northeastern Oklahoma, including Tulsa County.
Croisant, a former teacher, coach, and businessman, focused his campaign on expanding Medicaid, lowering the cost of living, and creating an accessible path to citizenship for long-term undocumented residents. While the candidates differed on immigration and healthcare, both listed the protection of Social Security as a priority.
