Supreme Court blocks Missouri map reinstatement

US Supreme Court blocks Missouri map switch, Justice Kavanaugh leaves state court ruling in place, midterm campaigns run on districts that may no longer exist

With less than two months until the US midterm elections, the Supreme Court has blocked a federal judge’s order that would have reinstated Republican-drawn congressional districts in Missouri, according to The Guardian’s US politics live coverage. The brief decision by Justice Brett Kavanaugh left standing a Missouri Supreme Court ruling that the new maps were not valid until approved by a public referendum, pushing the state back toward its earlier boundaries.

The sequence described by The Guardian shows how redistricting fights now move through parallel court systems at election speed. Missouri Republicans redrew the maps to split a Democrat-controlled district around Kansas City, a change that would likely have secured the party an additional Republican-leaning House seat in a state with eight seats. After the state court said the maps required a referendum, Missouri leaders appealed to the US Supreme Court; Kavanaugh’s order, issued without noted dissents, blocked a federal judge in St. Louis whose conflicting ruling had directed the state to use the Republican-favored maps.

Missouri Republicans argue that reverting to earlier boundaries close to election day could cause administrative chaos, The Guardian reports. That claim is not theoretical: the state held its primaries using the new GOP-leaning districts, meaning candidates won nominations in lines that may not exist for the general election. The legal fight therefore does not just decide which party benefits from which map; it also decides whether parties and voters are asked to treat the primary as a binding step in a process whose basic geography is still unsettled.

The case sits inside a national arms race over district lines, encouraged openly from the top. The Guardian reports that Trump urged Republican state leaders to gerrymander districts to help retain control of Congress, and that Democrats responded with a retaliatory redistricting effort. That escalation pushes the costs of uncertainty onto election administrators and candidates, while the potential payoff—one more seat here, one more firewall there—accrues to party leadership.

The court’s intervention is also its refusal to intervene in the way Missouri Republicans sought. By leaving the state court ruling in place, the Supreme Court effectively told state leaders that a late-stage map change that has already been challenged and procedurally questioned is not guaranteed a federal rescue, even if the election calendar is already running.

Missouri’s primaries were conducted under the newer lines, The Guardian reports. The general election may now proceed under different ones.
