Quality controls

All numerical fields are sourced from the same public election record. We do not interpolate, extrapolate, or estimate missing values.
Candidate posts with insufficient data (missing district, missing party, no recorded votes, or no rank) are marked as noindex until source data is complete.
Aggregates (party win rates, district margins) are re-derived from the underlying records — they are never hand-edited.

Corrections

If you spot a factual error, please use the Contact page. Corrections to source data flow through to all derived pages on the next sync cycle.

No paid content

We do not accept paid placement, sponsored candidate profiles, or affiliate links. We do not allow candidates or parties to modify their own profile copy.
