Missouri’s governor signed the state’s new congressional map into law Wednesday afternoon, leaving just three states without a finalized map after the 2020 census and redistricting process.

GOP Gov. Mike Parson approved the map the state Senate signed off on last week. Despite months of squabbling, the state’s new map has exactly the same partisan breakdown, though the lines have been redrawn. The state has roughly six Republican districts and two Democratic ones.


Parson expressed his displeasure with the delay following the signing.

"Today, we signed into law a congressional map that meets our constitutional requirements," Parson said. "This past session, we saw a few individuals' political posturing obstruct key pieces of priority legislation and promote inefficient and ineffective government. It's unfortunate so much time and productivity were lost just to receive a map with the same partisan split that was proposed six months ago. These past months could have been better used by county clerks implementing a new map and preparing for upcoming elections."

Republicans — who control both chambers of the legislature, 24-10 in the state Senate and 114-48 in the state House — couldn’t decide how aggressively they wanted to draw the state’s new map.

The state Senate’s seven-member conservative caucus had been lobbying for a map that would give Republicans another district.

Last week, the Senate approved the new map in a 22-11 vote before adjourning a day before the legislative session was set to end. Every member of the conservative caucus voted against the new map.

Parson finalized the map a little less than three months before the state’s primary contests begin Aug. 2. Because there is so little time between the map being approved and contests beginning, Republican Secretary of State Jay Ashcroft warned there might be problems lining voters up with their new districts. As a result of the delay, some voters might receive the wrong ballots.

Earlier this month, Ashcroft suggested it would be better for Missouri to hold its primary contests according to the old map. However, that solution might not be viable because the old map was based on the 2010 census. The state saw several lawsuits contending that Ashcroft’s suggestion was unconstitutional.

Following Wednesday’s signing, only New York, Florida, and New Hampshire still have outstanding problems with their congressional maps.


New York recently had a special master draw a new map that could devastate Democrats’ gains in the state and is already pitting high-profile lawmakers against each other. The New Hampshire Supreme Court has reminded the legislature that it is prepared to take over the map-drawing process if lawmakers cannot make a decision themselves. And a judge in Florida struck down a map that lawmakers and GOP Gov. Ron DeSantis have battled over for months.
