Review context
These calculated indicators are prompts for checking source data, reporting grain, denominators, and local context. They are not evidence or findings of fraud, misconduct, or an incorrect election outcome.
Average President-vs-down-ballot difference crossed threshold: DEM 9.39%, REP -7.89%.
The average gap between presidential votes and same-party down-ballot votes is large enough to review. Split-ticket voting can explain some gap; this flag identifies areas needing supporting records.

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
