The Supreme Court's recent ruling has effectively barred Missouri from implementing a new congressional map that favored Republicans, marking the third time this month the court intervened.12378912

Absentee voting commenced under the existing 2022 districts, amidst a backdrop of legal uncertainty that has left over a million voters confused.5

“At this late date, ordering reversion to the 2025 map in the midst of an ongoing election would usher in electoral chaos,” the court stated in an unsigned opinion.1011

The Missouri Supreme Court had previously ruled that a citizen petition necessitates voter approval for any new map, a decision upheld by the Supreme Court.

This ruling means voters will use the same districts as in the 2022 and 2024 elections, despite Republican hopes that the new map could secure additional seats in Congress.

The legal battles have caused significant confusion for nearly one in four Missouri voters, who have been shifted between districts, leading to different candidates on their ballots.

“Switching districts between the primary and general elections would violate the US constitution,” stated a panel of the Eighth Circuit Court of Appeals.4

As absentee voting began, local officials advised caution due to the ongoing legal disputes surrounding the congressional map.

Key Insight
“The decision means Missouri residents will vote under the same congressional districts used in the 2024 and 2022 elections. The high court warned that ordering reversion to the 2025 map would usher in 'electoral chaos,' and noted that more than a million potential voters were shifted between districts.”
