**Mike Mazzei holds a strong 72.5% implied probability in the August 25 Republican runoff for the Oklahoma gubernatorial nomination, ahead of Attorney General Gentner Drummond at 27.5%, with all other primary candidates at 0.1%.** The positioning stems from the June 16 primary results, where Drummond narrowly edged Mazzei (roughly 26.3% to 26.0%) to advance from a crowded field that included Chip Keating, Charles McCall, and Jake Merrick. Mazzei benefited from President Trump’s endorsement as a “MAGA warrior,” which consolidated support among Trump-aligned Republican voters who view him as the more conservative option focused on eliminating income taxes, reducing regulations, and restricting foreign land ownership. His heavy self-funding (over $11 million) has supported aggressive campaigning in a state where the GOP primary typically decides the general election outcome. Drummond’s advantages center on his statewide name recognition and record as attorney general, including actions against out-of-state interests, but polls show him with higher unfavorables and weaker appeal among the most conservative primary voters. Recent early-August runoff polling indicated a statistical tie at around 44% each, with Mazzei leading among men and rural voters while Drummond performed better with women and in metro areas. The four-day window before the runoff leaves limited time for shifts, though late developments in turnout or messaging could still influence the result in this closely contested race.
