Missouri enacted new congressional district boundaries on May 18 when Gov. Mike Parson (R) signed them into law. Missouri was apportioned eight seats in the U.S. House of Representatives after the 2020 census, the same number it received after the 2010 census. This map will take effect for Missouri’s 2022 congressional elections.
The Missouri House of Representatives approved the final version of the new congressional districts—HB 2909—on May 9 by a vote of 101-47. Eighty-six Republicans and 15 Democrats approved the new map and 28 Democrats and 19 Republicans voted against it. The state Senate approved the redistricting legislation on May 11 by a vote of 22-11. Sixteen Republicans and six Democrats voted to approve the new map and seven Republicans and four Democrats voted against.
According to Rudi Keller of the Missouri Independent, “No change in the partisan makeup of the Missouri delegation, currently six Republicans and two Democrats, is expected as a result of the map.”
After Senate passage, State Sen. Mike Bernskoetter (R) said, “I believe the new map does a good job of balancing Missouri’s regions and their different views. It meets all the requirements we are constitutionally obligated to meet.”
As of May 25, 42 states have adopted new congressional maps, six states were apportioned one congressional district (so no congressional redistricting is required), Florida’s map was overturned by a court decision that is under appeal, and New Hampshire has not yet adopted congressional redistricting plans. As of May 25 in 2012, 42 states had enacted congressional redistricting plans.
States have completed congressional redistricting for 406 of the 435 seats (93.3%) in the U.S. House of Representatives.
