NATIONWIDE — Several U.S. states have moved to redraw congressional district maps ahead of the November 2026 midterm elections, breaking from the typical practice of redistricting once per decade after each census. Officials in more than a dozen states have considered or proposed mid-decade redistricting plans, with six states adopting new maps since summer 2025.

Florida Governor Ron DeSantis called a special legislative session to begin on April 20, 2026, to consider congressional redistricting. As of April 14, Florida Republicans had not publicly released a proposed map. Florida currently has 20 Republican and eight Democratic congressional districts. The Florida Constitution prohibits drawing districts with the intent to favor or disfavor a political party or incumbent.

In Virginia, the Democratic-led General Assembly approved a proposed U.S. House map requiring a constitutional amendment to take effect. The amendment is on the ballot in April 2026 after the Virginia Supreme Court ruled the referendum could proceed. The court is also considering an appeal of a Tazewell County judge's ruling that invalidated the amendment due to procedural violations by lawmakers. Virginia currently has six Democratic and five Republican districts.

The redistricting wave followed President Donald Trump's 2025 urging of Texas Republicans to redraw districts for partisan advantage. Texas Governor Greg Abbott signed a revised map into law in August 2025, projected to allow Republicans to win five additional seats. In December 2025, the U.S. Supreme Court stayed a lower-court ruling that had blocked the map on racial gerrymandering grounds, allowing it to be used in 2026. California Democrats initiated redistricting in response, and voters approved revised districts in November 2025, projected to yield five additional Democratic seats. In February 2026, the Supreme Court denied an appeal by Republicans and the Department of Justice, leaving the California map in place.

Missouri Governor Mike Kehoe signed a revised congressional map in September 2025, projected to allow Republicans to win one additional seat. A Cole County judge ruled the districts are in effect while officials review a referendum petition. The Missouri Supreme Court rejected a lawsuit claiming mid-decade redistricting is illegal but is scheduled to hear arguments in May 2026 on claims the districts violate compactness requirements.

Maryland's redistricting effort stalled. The House of Delegates passed a plan in February 2026 supported by Governor Wes Moore, projected to gain Democrats one seat, but the session ended in April without the state Senate voting on it. Maryland currently has seven Democratic and one Republican district.

In New York, a judge ordered a state commission in January 2026 to redraw the only Republican-held congressional district in New York City, ruling the existing district diluted the votes of Black and Hispanic residents. In March 2026, the Supreme Court granted Republicans' request to halt the order, leaving existing lines in place for 2026. Of the six states that adopted new maps, four did so voluntarily, one was required by the state constitution, and one acted under a court order. In at least five additional states, redistricting proposals failed to advance or were struck down by courts.
