Context

NBC News Decision Desk analysts examined how national partisan shifts from the 2024 baseline would translate into House seats ahead of the 2026 midterms. They use three indicators: polling, past vote patterns and special election results.

The analysis says Democrats are favored to win the House, but Republican-drawn maps and incumbency could limit the size of any Democratic gain. Results in individual districts may diverge from the national trend.
