Counts are active registered voters from each state's public voter file as of VoterVault's latest ingest — they may differ slightly from official Secretary of State reports. Ohio has no party registration: the file derives party from the most recent partisan primary each voter pulled, so "Unaffiliated" simply means no recent primary ballot. Turnout tiers score participation in recent even-year November general elections from public vote history. Aggregate market data only — no personal information is shown on this page. Public-record data sold for lawful political/electoral use; VoterVault performs no outreach and is not affiliated with any election authority.
