equipment_contextVerified Voting Verifier MD 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.

Equipment Cluster DiagnosticThis checks whether currently flagged jurisdictions cluster by vendor/system group inside the selected state. 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.
Context only| Vendor | Systems | Jurisdictions | Poll-book types |
|---|---|---|---|
| ES&S | 1 | 24 | 1 |
| Group | Flagged | Rate | Jurisdictions | Lift | Status | Caveat |
|---|---|---|---|---|---|---|
| ES&SES&S ExpressVote + | 0 | 0.0% | 24 | N/A | Limited | No local review rows are loaded for this state, so advisory flags have not been evaluated and this is a coverage summary rather than a cluster check. Controls: same selected state - same imported jurisdiction level - current advisory flag set only - vendor/system grouping from Verified Voting Verifier jurisdiction fields - no claim that every precinct or ballot mode used one identical setup. |
