Open Senate margin, 2026 on the map
What this measure is
The Republican candidate's votes minus the Democrat's, as a share of the two candidates' votes, in percentage points: R+10 means the Republican led by 10 points, D+10 the Democrat. Only the 35 states with a Senate race in 2026 have figures, and a race without both a Democrat and a Republican on the ballot has none (Idaho, Nebraska and South Dakota, where an independent was the main challenger). 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.
