Party registration

Ohio doesn't register voters by party, so there's no party breakdown to show. Party lean is usually inferred from primary participation — that data is in the voter file and available inside Motion51.

Supervoters are active registered voters who cast a ballot in at least 3 of the last 4 November general elections (2018–2024). Percentages are precinct totals from the official state voter file — no individual voter information is shown. Precincts with fewer than 400 active voters are excluded.
