Not shown for state legislators — and why
The federal profiles on this site lead with votes, legitimacy and campaign finance. Those aren't published for state seats in any single feed, so they're absent here rather than estimated:
- Roll-call votes — No single national feed publishes state roll-call votes; surfacing them means scraping each chamber into the ETL.
- Legitimacy & turnout — Needs citizen voting-age population (CVAP) by state-legislative district joined to certified election returns.
- Campaign & outside money — State contributions and independent expenditures live in 50 separate disclosure systems, not the FEC feed used for Congress.
