Supreme Court blocks Missouri's new congressional map, forcing return to 2022 districts

Last week the Supreme Court issued a terse order preventing Missouri from using a newly drawn congressional map that had been championed by Donald Trump and state Republicans. As a result, Missouri will revert to the 2022 district configuration for the November midterms, even though the August primary was conducted under the contested map. The new plan would have moved portions of Rep. Emanuel Cleaver's Kansas City district into more Republican-leaning areas, potentially making the seat more winnable for the GOP.

Republicans were targeting seven of the state's eight House seats, but the court's decision leaves them with six. The shift may affect over a million voters, roughly a quarter of the electorate, creating confusion as many will find themselves in different districts than those they voted in during the primary. Election officials and candidates now have to adjust to the older boundaries with only weeks before the vote.
