Congressional redistricting efforts are intensifying across the nation as states compete for political advantages before November’s midterm elections, with fewer opportunities remaining and deadlines approaching fast.
Maryland’s legislative session concluded this week, ending Democratic hopes to redraw the state’s congressional districts. Meanwhile, Florida legislators will convene Monday for a special session focused on Republican redistricting efforts. Virginia residents will vote Tuesday on a Democratic redistricting proposal that could deliver several additional House seats to the party this election cycle.
Congressional maps are traditionally redrawn every ten years following the census. However, former President Donald Trump sparked an uncommon mid-decade redistricting wave last year by encouraging Texas Republicans to alter House districts for GOP benefit in the midterms. California Democrats responded in kind, triggering redistricting movements nationwide.
Current projections suggest Republicans could secure nine extra seats in states where they’ve redrawn congressional boundaries, while Democrats anticipate gaining six seats through redistricting elsewhere. These estimates assume historical voting trends continue into November, though uncertainty remains high given that the governing party typically loses midterm seats and Trump faces unfavorable poll numbers.
Democrats require only a small number of additional seats in November to reclaim House control from Republicans, potentially enabling them to block Trump’s legislative priorities.
More than twelve states have considered or proposed redistricting measures. Current attention centers on two states with opposing party leadership.
Current composition: eight Democrats, 20 Republicans
Proposed changes: Republican Governor Ron DeSantis has scheduled a special legislative session starting Monday to address congressional redistricting. Republicans have not yet revealed their specific redistricting strategy.
Legal obstacles: The state constitution prohibits drawing districts with the intention of favoring or disadvantaging any political party or incumbent officeholder.
Current composition: six Democrats, five Republicans
Proposed changes: A new congressional map approved by the Democratic-controlled General Assembly could assist Democrats in winning up to four additional seats. Implementation requires voter approval of a constitutional amendment permitting mid-decade redistricting, which appears on Tuesday’s ballot.
Legal obstacles: The state Supreme Court authorized the referendum to proceed but has not determined the effort’s legality. The court is reviewing an appeal of a Tazewell County judge’s decision declaring the amendment invalid due to lawmakers violating procedural rules during passage.
Six states have implemented new congressional districts since last summer. Four states pursued redistricting voluntarily, one was mandated by state constitutional requirements, and another acted under judicial order.
Current composition: 13 Democrats, 25 Republicans
New configuration: Republican Governor Greg Abbott enacted a revised House map last August that could help Republicans secure five additional seats.
Legal obstacles: The Supreme Court cleared the path in December for using the new districts in this year’s elections, suspending a lower court decision that blocked the map for being “racially gerrymandered.”
Current composition: 43 Democrats, nine Republicans
New configuration: Voters approved revised House districts in November drawn by the Democratic-controlled Legislature that could help Democrats gain five additional seats.
Legal obstacles: The Supreme Court permitted the new districts for this year’s elections in February, rejecting appeals from Republicans and the Justice Department claiming the districts improperly favor Hispanic voters.
Current composition: two Democrats, six Republicans
New configuration: Republican Governor Mike Kehoe enacted a revised House map last September that could help Republicans gain one additional seat.
Legal obstacles: A Cole County judge ruled the new map takes effect while election officials determine if a referendum petition meets constitutional standards and contains sufficient valid signatures. The Missouri Supreme Court dismissed claims that mid-decade redistricting is illegal and will hear arguments in May regarding allegations the new districts violate compactness requirements and should be suspended pending the potential referendum.
Current composition: four Democrats, 10 Republicans
New configuration: The Republican-controlled General Assembly finalized revised districts in October that could help Republicans win one additional seat.
Legal obstacles: A federal court panel denied a November request to prevent the revised districts from being used in midterm elections.
Current composition: five Democrats, 10 Republicans
New configuration: A bipartisan panel with Republican majority approved revised House districts in October that enhance Republicans’ prospects of winning two additional seats.
Legal obstacles: None exist. The state constitution mandated new districts before the 2026 election because Republicans had previously approved maps without adequate Democratic support following the last census.
Current composition: no Democrats, four Republicans
New configuration: A judge implemented revised House districts in November that could help Democrats win one seat. The court determined lawmakers had bypassed voter-approved anti-gerrymandering standards when adopting the previous map.
Legal obstacles: Both a federal court panel and the state Supreme Court rejected Republican challenges to the judicial map selection in February.
Governors, legislators, and partisan officials advocated for congressional redistricting in multiple states. At least five states saw these efforts gain initial momentum before ultimately failing in either legislative bodies or courts.
Current composition: seven Democrats, one Republican
Proposed changes: The Democratic-controlled House passed a redistricting plan in February supported by Democratic Governor Wes Moore that could help Democrats win one additional seat.
Legal obstacles: The legislative session concluded in April without the Democratic-led Senate voting on the redistricting proposal. The Senate president cited concerns it might harm Democratic interests.
Current composition: 19 Democrats, seven Republicans
Proposed changes: A judge ordered a state commission in January to redraw boundaries for New York City’s only Republican-represented congressional district, ruling it unconstitutionally weakens Black and Hispanic voting power.
Legal obstacles: The Supreme Court granted Republicans’ request in March to stop the judge’s order, maintaining existing district boundaries for the 2026 election.
Current composition: two Democrats, seven Republicans
Proposed changes: The Republican-controlled House approved a redistricting plan in December that would have enhanced Republicans’ chances of winning two additional seats.
Legal obstacles: Despite Trump’s pressure to adopt the new map, the Republican-led Senate rejected it in a bipartisan vote on December 11.
Current composition: one Democrat, three Republicans
Proposed changes: Several Republican lawmakers attempted to initiate congressional redistricting.
Legal obstacles: Lawmakers abandoned a petition drive for a special redistricting session in November after failing to secure sufficient support.
Current composition: 14 Democrats, three Republicans
Proposed changes: The Democratic Congressional Campaign Committee proposed a new congressional map in October that would improve Democrats’ chances of winning one additional seat.
Legal obstacles: The Democratic-controlled General Assembly refused to pursue redistricting, expressing concerns about impacts on Black representation.
