On March 8, Paul Berry, a Republican congressional candidate, filed a lawsuit in state court, complaining about the failure of the legislature to have redrawn new U.S. House districts. Berry v State, 224c-cc00103, Cole County Circuit Court. This lawsuit is unusual because it does not involve partisanship. The Missouri legislature has a Republican majority in both houses. The House has passed a plan for new U.S. House districts, but the Senate has not. Here is the Complaint. Berry wants the court to draw the districts.
The primary is in August and the deadline for candidates to file for the primary is March 29. Independent candidate petitions are due in late July. Thanks to Ken Bush for the link.
