Open House vote margin, 2026 on the map
What this measure is
Votes for Republican House candidates minus votes for Democratic candidates, as a share of the two parties' votes, in percentage points: R+10 means Republicans won the area's House vote by 10 points, D+10 Democrats. Only districts with both a Democrat and a Republican on the ballot count, and a county split between districts adds its votes in each. These are unofficial results still being counted, so figures move as late ballots are added and certified results can differ. White stripes over the colour mark low reliability: under 95% of precincts reporting, or part of the area in an uncontested district.
