In less than a month, Missouri opponents of U.S. House redistricting have collected half the signatures they need to force a referendum on the bill that changes the districts. The campaign has until December to finish the petition. The effort has 3,100 volunteer petitioners. Assuming enough signatures are collected, the new law can’t go into effect until after the voters vote on the bill. Therefore, the bill would not be in effect for the 2026 election, and the old district boundaries would be used.
