With the news that President Donald Trump is tapping U.S. Senator Markwayne Mullin (R-OK) to be the new Department of Homeland Security secretary, the 2026 Oklahoma election cycle has been thrown into another round of chaos.
Assuming Mullin's almost-certain confirmation, that will necessitate an interim appointment by Gov. Kevin Stitt to fill out the remainder of Mullin's Senate term (through January 2027). By Oklahoma statute, a temporary appointee pledges to not run for the full-term position. Thus, the appointee will be a lame-duck placeholder, while a fresh slate of candidates will compete for the full 6-year Senate term in the November 2026 election.
