Margins are the Democrat minus the Republican in points of all votes cast in that race, from the counts the state’s election office has published so far; a county still counting is compared on what it has counted in both. A difference is not a count of split tickets: a voter who skipped one race moves it too.

Counts are Oklahoma’s official state and county counts. Where a race is still being counted, its margin is where we expect the count to finish, marked *. A move from 2024 is the 2026 margin against Kamala Harris’s margin over Donald Trump in the same place. A race is won when we call it or the state certifies it.
