What this measure is
The 2026 House margin minus the 2024 House margin, both as a share of the two parties' votes and counting only districts with a Democrat and a Republican on the ballot: R+5 means the area moved 5 points toward Republicans, D+5 toward Democrats. District lines changed in several states between the two elections (Texas, California, North Carolina, Missouri, Ohio, Utah and others), so an area can compare different contests. The 2026 results are unofficial and still being counted. White stripes over the colour mark low reliability: under 95% of precincts reporting, or part of the area uncontested in either year.
