Official Connecticut EMS static JSON town result and turnout packageAdministration context
No county-tagged vote-method rows are available.
Administration context
Equipment metadata is jurisdiction context only. It is not a vote or turnout row, does not prove or disprove an advisory signal, and does not guarantee every precinct or ballot mode used one identical setup.
No county-tagged equipment context is available.
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 -1.26%, REP 4.80%.
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.
Vote-share correlation crossed threshold: Trump r=-0.410, Harris r=0.655.
Bigger local reporting-unit vote totals move with candidate vote share strongly enough to pass the native review threshold. This is an advisory review flag, not proof of tampering.
