Refresh Cadence
| Data type | Cadence | Notes |
|---|---|---|
| Campaign finance (current members) | Hourly | FEC receipts, cash on hand, outside spending. |

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 — see methodology for details.
