The constitutional loophole that shaped a Missouri governorship

In short: How does a politician enter the highest office in the state without first winning an election? Mike Kehoe’s rise to the Missouri governorship involved a high-stakes legal battle over the limits of executive power and the specific wording of state law.

Mike Kehoe's path to the governorship began with a controversial appointment in 2018. When a vacancy occurred in the office of lieutenant governor, Governor Mike Parson appointed Kehoe to the role. However, this move was immediately met with legal challenges. A specific state law suggested that the governor lacked the authority to fill vacancies for the lieutenant governor, while the Missouri Constitution stated that the governor could fill all public office vacancies unless otherwise provided by law.

The resulting legal dispute reached the Missouri Supreme Court. The case centered on whether the state law's restriction was clear enough to override the broader constitutional authority. In April 2019, the court ruled 5–2 in favor of Kehoe's appointment. Chief Justice Zel Fischer wrote that Governor Parson was within his constitutional authority, citing the vagueness of the state law as a reason for the ruling. This victory allowed Kehoe to serve as lieutenant governor until he was elected to the position in his own right in 2020.

Kehoe's subsequent political career has been defined by significant legislative actions and fiscal policy shifts. As governor, he signed a 2025 law repealing a voter-approved measure that would have increased the minimum wage and guaranteed paid sick leave. He has also prioritized the MOScholars program, proposing a $50 million budget allocation for private and parochial school tax credits, a move that drew criticism from Democrats who argued it privatizes education. His platform continues to focus on major tax overhauls, including a proposed 2026 amendment to eliminate the state's income tax entirely.

Beyond policy, Kehoe's career reflects a transition from the private sector to public service. Before entering politics, he worked for Osage Industries, a manufacturing company, and owned an auto dealership. His rise illustrates the intersection of private business experience and the complex, often ambiguous legal frameworks that govern how executive power is exercised in American state government.
