Michigan's 31st Senate district


Michigan's 31st Senate district is one of 38 districts in the Michigan Senate. The 31st district was created by the 1850 Michigan Constitution, as the 1835 constitution only permitted a maximum of eight senate districts. It has been represented by Republican Roger Victory since 2023, succeeding fellow Republican Kevin Daley.
