Verified Voting
Verified Voting Verifier data is jurisdiction-level election-administration context. Most rows are counties, but some states report state-level rows and some county rows can summarize mixed tabulation, accessible-device, absentee, poll-book, or other configurations. Treat it as source-linked context, not proof every precinct in a county used one identical setup, and not a turnout or vote-result source.Open source
