The 8th Circuit Court of Appeals ruled Monday that Missouri must use a Republican-drawn congressional map for the November 2026 midterm elections, reversing lower court decisions that had blocked the redistricting plan.

The three-judge panel determined the GOP map would cause less voter confusion than alternatives because Missourians already used it during this year's primary election on September 4. The court gave opponents one week to seek emergency relief from the U.S. Supreme Court before the map takes effect.

Missouri Republicans redrew congressional boundaries in 2025 in a plan expected to eliminate one of the state's two Democratic House districts. The new map consolidates Democratic voting strength in St. Louis and Kansas City into a single district, potentially flipping the current 6-2 Republican advantage to 7-1.

Legal Battle Timeline

The redistricting fight has bounced between state and federal courts for months. Missouri's Supreme Court initially ruled the new map never legally took effect, requiring the state to use the 2022 boundaries for November.

Republican officials appealed to federal court, arguing the state ruling created impossible conflicts with election administration. The 8th Circuit sided with the GOP on Monday, finding that reverting to old maps so close to the general election would create more problems than keeping the primary maps in place.

Secretary of State Jay Hoskins had rejected a referendum petition seeking to let voters decide on the redistricting plan. He ruled on September 4, the same day as the primary, that Missouri's constitution does not authorize referendums on congressional maps.

Democratic Opposition

Democrats and voting rights groups immediately criticized the decision. Democracy advocates argue the rushed timeline prevents proper judicial review and denies voters meaningful input on boundaries that will shape representation for the next decade.

The appeals court did not rule on underlying constitutional challenges, including Equal Protection and Elections Clause claims. Those issues remain unresolved even as the map proceeds toward use.

Missouri mailed absentee ballots weeks ago based on uncertainty about which districts would apply. Election officials now face the prospect of voters receiving ballots reflecting outdated boundaries if the Supreme Court declines to intervene.

The one-week window for Supreme Court review puts the redistricting question on an accelerated track. Justices have already weighed in twice on Missouri's maps this cycle, blocking an earlier attempt to implement the GOP plan before more complete briefing.

Republicans defend the map as a legitimate exercise of legislative authority to draw district lines. They point out both parties engage in redistricting to maximize political advantage when they control state governments.
