Interactive map shows possible outcomes for control of the House
An NBC News graphic lets readers model scenarios in which Democrats gain a majority or Republicans retain control of the House of Representatives.
An interactive graphic from NBC News lets users explore how the 2026 congressional elections could affect control of the U.S. House of Representatives. Currently, Republicans hold 219 seats, Democrats 214, with two seats vacant. Democrats would need a net gain of three seats to secure a majority, while Republicans aim to preserve their lead. The analysis notes that many competitive districts are in states President Donald Trump won in 2024, and that redistricting efforts last year gave Republicans a structural edge. Users can adjust variables to see how different outcomes might shape the size of a Democratic majority or allow Republicans to hold onto the chamber.
