Notes on Coverage
- Coverage and detail can vary by office and historical period.
- Some historical profiles use curated local overrides when upstream APIs cannot resolve a Bioguide ID.
- Empty fields are retained to avoid implying data that is not available.
- Net-worth estimates are range-based calculations from disclosed asset/liability bands, not exact balances.
