Notable personal detailsMike Mazzei is an Oklahoma Republican politician and financial planner who served in the Oklahoma State Senate (District 25) from 2004 to 2016 and later served as Oklahoma Secretary of Budget in Governor Kevin Stitt’s administration (2019–2020). He announced a run for Governor of Oklahoma in the 2026 election cycle and filed for the office in April 2026. He is based in Tulsa, Oklahoma and has five adult children.
Supports major tax reductions including phasing out property taxes and eliminating the state income tax through a multi-phase plan; emphasizes cutting waste, reducing tax rates (proposes lowering the income tax from 4.75% to 3.25%), and fiscal discipline to preserve essential services while shrinking tax burdens.
Mike Mazzei, while serving as Oklahoma’s budget secretary, supported pursuing a state-specific Medicaid approach (a waiver/’Medicaid 2.0’ style plan) focused on implementation details such as premiums, work requirements, and controlling state costs rather than straightforward ACA-style expansion. His campaign materials emphasize fiscal restraint and rejecting federal mandates tied to funding, and he has highlighted budgetary concerns when discussing Medicaid expansion. There is no campaign page endorsing Medicare for All or a universal public option.
The candidate supports strong enforcement measures and frames unauthorized immigration as a security threat, calling for protecting Oklahoma from foreign ownership and ‘illegal aliens’ and endorsing cooperation with federal authorities to defend borders and public safety. His campaign emphasizes expelling or blocking foreign hostile ownership of land and backing law-enforcement-focused responses to immigration-related risks.
The candidate supports eliminating abortion in Oklahoma with narrow exceptions to protect the life of the mother and describes a 100% pro-life voting record from his time in the state Senate. He endorses returning authority over abortion to the states and seeks statutory language to end abortion while preserving life-threatening medical exceptions. He opposes unrestricted access and supports parental-consent style restrictions for minors.
The candidate emphasizes protecting Oklahoma energy resources and supports oil and gas production alongside other energy sources, criticizes 'green energy' policies he sees as harmful to the state economy, and favors market-driven approaches and limited tax incentives for energy. He has proposed limiting certain tax exemptions for marginal oil wells to protect state revenues.
Supports broad gun-carry rights and has publicly backed constitutional-carry policies; is affiliated with Oklahoma Second Amendment advocacy groups. Positions emphasize Second Amendment protections and reducing permitting requirements for carrying firearms.
Mike Mazzei remains the heavy favorite in the Oklahoma GOP governor nominee market even after fresh reporting on Trump’s May 29 endorsement, keeping the race’s repricing centered on the Mazzei-vs.-Keating split ahead of the June 16 primary.
Donald Trump backed Mike Mazzei for the Oklahoma Republican governor nomination, and Mazzei is currently at 21%.
