Republican Mike Mazzei has defeated Democrat Cyndi Munson in Oklahoma’s gubernatorial election, securing the governorship and becoming the state’s 29th governor. The Associated Press called the race for Mazzei at 11:46 p.m. Eastern on November 3, giving Republicans another victory in a state that has consistently backed the party in recent statewide and presidential elections.

Mazzei, a Tulsa businessman and former Oklahoma state senator, will succeed Republican Gov. Kevin Stitt, who was unable to seek another term because of term limits. His victory continues Republican control of the governor’s office, which Democrats have not held since Brad Henry left office in January 2011.

President Donald Trump played a significant role in Mazzei’s path to the governor’s mansion. Trump endorsed him during the Republican primary and later traveled to Oklahoma to campaign alongside him at a rally in Durant. The president urged voters to support Republican candidates, while Mazzei appeared with him as the party worked to maintain its hold on the state.

Mazzei's nomination came after a competitive Republican primary that began with nine candidates. He advanced to an August runoff against Oklahoma Attorney General Gentner Drummond, ultimately defeating him by a narrow margin. Mazzei received approximately 50.3% of the runoff vote, narrowly securing the nomination after a closely contested campaign. Trump's endorsement helped establish him as a leading candidate in the race.

The governor-elect brings extensive experience in Oklahoma government and the private sector. He represented Senate District 25 from 2004 through 2016, where he chaired the Senate Finance Committee and developed a reputation around state budget and tax issues. After leaving the Legislature, Mazzei served as Oklahoma's Secretary of Budget before returning to the private sector. He also leads a Tulsa-based investment management firm, drawing on his financial background throughout his campaign.

Mazzei made economic policy a central part of his bid for governor. He campaigned on eliminating Oklahoma's state income tax, pursuing additional tax relief and reducing regulations that he argued could discourage business investment. His broader economic agenda focused on attracting employers, expanding opportunities for high-paying jobs and keeping Oklahoma competitive with other states.

He also called for stronger protections against foreign ownership of Oklahoma land, particularly as concerns over foreign investment in American agricultural property have become a larger issue nationally. On education, Mazzei emphasized improving literacy, strengthening math and science instruction and expanding career and technical education opportunities for students entering skilled trades.

Energy development and Oklahoma's economic future were also important parts of his campaign. Mazzei discussed the state's role in the energy industry and the growing demand for electricity from large-scale data centers. The issue became part of the broader gubernatorial debate as Oklahoma communities and lawmakers considered how to balance economic development with the demands new facilities place on local power infrastructure.

Munson, the Democratic leader in the Oklahoma House of Representatives, challenged Mazzei on education, healthcare and the cost of living. She represented an Oklahoma City district and had served in the Legislature since 2015. Her campaign argued for greater investment in public services and changes to state tax policy, but she was unable to prevent Republicans from retaining the governor's office.

Mazzei's election gives Republicans another opportunity to advance their agenda in a state where the party holds a strong statewide advantage. His background in state budgeting and investment management is likely to shape his approach to taxation, government spending and economic development when he takes office.

Mazzei will be sworn in as Oklahoma's next governor in January 2027, succeeding Stitt after eight years in office. His victory completes a campaign that began in a crowded Republican primary, continued through a narrow runoff and ended with his election to lead the state.
