Trump-endorsed Mike Mazzei wins Oklahoma GOP runoff after defeating Genter Drummond

Mike Mazzei won Oklahoma’s Republican gubernatorial runoff election, defeating Genter Drummond, according to Fox News. The result sets up Mazzei to face the general-election contest for governor as the GOP nominee from Oklahoma’s primary runoff process.

Fox News reported that Mazzei had secured an endorsement from President Donald Trump ahead of the runoff. In Oklahoma, where Republicans hold statewide offices and the GOP primary determines much of the general-election outcome, an endorsement from the president can be central to party momentum, fundraising, and voter outreach, though Fox did not provide additional details on the endorsement’s timing or campaign operations around it.

On the policy front, Mazzei told voters he would pursue eliminating Oklahoma’s income tax if elected governor, Fox News reported. The pledge, as described in the reporting, frames the campaign’s central fiscal objective and points to a potential shift in how state government funds programs tied to income-tax revenue.

The runoff win also resolves a key intra-party hurdle for Mazzei. Rather than being determined in the initial primary, the nomination moved through a second election round, where the Republican electorate narrowed the field to the candidate most aligned with GOP voters. Drummond, as the runner-up, did not secure the nomination in the second round.

Because the reporting provided here is limited, additional details such as the final vote totals, turnout, and any formal campaign messaging or policy specifics beyond the income-tax pledge were not included. Any further assessment of how Mazzei’s proposal would be implemented would depend on Oklahoma statutory and budget processes, including what measures a governor can advance unilaterally versus what would require legislative action.

Mazzei’s next step, if he remains on course as the GOP nominee, will be to participate in Oklahoma’s general-election cycle. As the state moves toward the general election, voters and state lawmakers will likely focus on how any income-tax elimination effort would align with revenue needs, budget constraints, and constitutional requirements for state tax changes.
