Keith Regier’s political identity is marked by an ideological rigidity that manifests in unexpected ways, such as promoting conspiracy theories about COVID-19 vaccines. His legislative career, spanning from the Montana House of Representatives to the Senate, suggests a deeply localized approach, likely influenced by his business and teaching background.
