equipment_contextVerified Voting Verifier IL 2024 equipment contextLoaded
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.

Official precinct data turnout replacement reviewOfficial precinct data turnout replacement reviewDocumented exclusion
The official by-office precinct CSVs expose Registration and VoteCount fields, but the President CSV lacks an election-level ballots-cast field, has 2,260 precinct keys with zero Registration, and the reviewed registration/contest-total sums do not reconcile to active turnout benchmarks. Documented as a state-native lead that is not a valid turnout replacement.

It is review context only, not evidence of cause, does not prove a county is internally uniform, and it does not control for demographics, geography, or contest coverage.
