**Mike Mazzei leads the Oklahoma Republican gubernatorial runoff market at 78.8% against Attorney General Gentner Drummond at 22%, with all other candidates at 0.1% after failing to advance from the June 16 primary.** The race heads to an August 25 runoff because neither reached a majority in the first round, where Drummond narrowly edged Mazzei. Mazzei's dominant market position stems primarily from President Trump's endorsement and a recent campaign video calling him a "MAGA warrior" with complete support, which has mobilized conservative voters in the deeply red state. Recent polling shows a close contest, with one survey tying the candidates at 44% and another giving Mazzei a modest lead, though low runoff turnout often amplifies organized bases. Mazzei, a former state senator and financial adviser, emphasizes tax cuts including property tax relief for seniors and veterans, education reform, and business growth. Drummond, a former fighter pilot, highlights his record on cost-of-living issues, rural infrastructure, and tribal relations, backed by groups like law enforcement and agriculture. Additional factors include Mazzei's significant self-funding, differences over projects such as the Inola aluminum smelter, and broader campaign spending patterns. Traders appear to weigh the Trump factor and primary momentum as tilting the runoff toward Mazzei despite the tight polling.
