Electoral maps redrawn as US prepares for pivotal 2026 midterms
With the November 3 vote approaching, legal challenges and legislative maneuvers in Florida, Texas, Missouri, North Carolina, California, and Ohio are reshaping the House of Representatives and Senate landscape.
The United States is preparing for the midterm elections on November 3, 2026, a contest that will determine control of the House of Representatives and one-third of the Senate. These elections serve as the first major electoral verdict on President Donald Trump’s second term, following his 2024 victory over Kamala Harris. The electoral landscape is significantly shaped by recent redistricting efforts in key states, including Florida, Texas, Missouri, North Carolina, California, and Ohio. Republican-led redistricting in Florida, Texas, Missouri, North Carolina, and Ohio aims to secure or expand Republican majorities, often facing legal challenges alleging racial gerrymandering or violations of voting rights. Conversely, California adopted a Democratic-backed map via Proposition 50 to protect its existing majority. These changes reflect intense partisan battles over electoral boundaries.
Florida’s new congressional map, pushed into law by Governor Ron DeSantis, is expected to strengthen Republican control and could help the party gain up to four additional Republican-leaning districts. The previous map already favoured Republicans with Democratic voters concentrated around Orlando, Tampa and South Florida, including Miami. The redraw further clusters Democratic voters into fewer districts while expanding Republican-leaning areas across central and southern Florida. Voting rights groups and Democratic organisations filed lawsuits within days, arguing it violates Florida's "Fair Districts" antigerrymandering amendment.
Legal battles over redistricting also escalated in Texas, where the US Supreme Court reinstated the post-2020 congressional map drawn by Republicans on April 27. This map had been blocked by a lower court over allegations of racial gerrymandering. Civil rights organisations, including the American Civil Liberties Union, the League of United Latin American Citizens and the Mexican American Legal Defense and Educational Fund, have challenged the map in federal court, arguing it violates the Voting Rights Act by diluting minority representation.
In Missouri, Governor Mike Kehoe signed a new congressional map into law in September, which the Missouri Supreme Court upheld, clearing the way for its use in the 2026 elections. The new lines generally make most Republican-leaning districts in the rest of Missouri even harder for Democrats to win. Meanwhile, in October, the North Carolina Senate approved a new congressional map expected to make one more US House seat Republican-leaning, and Ohio approved a new congressional map in October, unanimously approved by the Ohio Redistricting Commission, which is expected to further strengthen Republican dominance.
California voters approved a new Democratic-backed map under Proposition 50, known as the Election Rigging Response Act, in a 2025 special election. The new boundaries are designed to help Democrats protect and potentially expand their existing 43-seat majority in the state. On May 13, the NAACP and a coalition of civil rights organisations filed a lawsuit in Tennessee against lawmakers who split the state’s only majority-Black district centred on Memphis. Six states held primary elections on a recent Tuesday: Alabama, Georgia, Idaho, Kentucky, Oregon, and Pennsylvania.
