Perkins won the Republican
primary election in August 2020 to replace fellow Republican incumbent
Jim Hansen, who could not seek reelection due to Missouri's constitutional
term limits. There was no
Democrat running for the 40th District. On May 27, 2021, the
St. Louis Post-Dispatch reported that when Perkins was working as a police officer in 2015, a report alleged he had received a "sexual favor" from an intoxicated 19-year-old. The woman also asked Perkins to help her get alcohol and the prescription drug
Adderall. The report also said Pike County Sheriff Stephen Korte had obstructed a probe into Perkins as he was running for office, saying, "do everything we can to get Chad elected". In January 2024, Perkins filed legislation to abolish the
death penalty, citing it as a
pro-life issue. In February 2025, Perkins filed a bill to indirectly remove Cotton Walker as
Cole County circuit court judge, telling media that he fundamentally disagrees with Walker's court decisions. == Electoral history ==
