Race calls and winners come from Wikipedia's
House,
Senate and
governor
results pages (CC BY-SA 4.0), which follow AP calls and can trail them by a few hours. Shading is by winner only; these tables do not include vote shares.
House hexagons are laid out inside the outline of the country, one per seat. The outline is squeezed where there are few seats (the Mountain West) and stretched where there are many (the Northeast), so states sit roughly where they are but not at their true size or exact place, and a district's position inside its state is approximate. "Party gain" follows Wikipedia, and includes seats that changed hands because district lines were redrawn.
Turnout: UF Election Lab (Michael McDonald), ballots counted as a share of the voting-eligible population. 2026 figures are early estimates until states certify; 2022 figures are final.
State and county boundaries: US Census Bureau, via us-atlas. Population: 2020 Census state totals, spread across counties using each county's share in earlier Census estimates. County-level vote counts are not shown because they aren't available yet. County lines date from 2017: Connecticut shows its former 8 counties (replaced by 9 planning regions in 2022), and Alaska's Valdez-Cordova area appears as one before its 2019 split.
