Oklahoma Republican Gubernatorial Runoff: Drummond vs. Mazzei
8/25/2026, 4:12:10 AM
Core Event
On June 16, Attorney General Gentner Drummond edged former state budget secretary Mike Mazzei in the Republican primary for governor, receiving 26.25 % of the vote to Mazzei’s 25.97 %. Because neither candidate reached a majority, a runoff is scheduled for August 25. The winner will become the GOP nominee for the November general election.
Background & Context
Governor Kevin Stitt is term-limited, leaving the GOP nomination open. The race pits national MAGA influence against local Oklahoma politics. President Donald Trump endorsed Mazzei before the primary, a move that historically boosts Republican primary prospects. In a departure from past practice, the Oklahoma Republican Party formally endorsed candidates in three runoff contests, including Mazzei for governor, sparking internal debate. Tribal-state relations also loom large: Stitt’s tenure featured legal challenges to tribal compacts, and both runoff candidates have pledged to work with tribal nations and uphold the Supreme Court’s *McGirt* decision.

Conflicting Reports & Gaps

The extent to which the party’s endorsement influenced voter perception remains unquantified.
