Open the dashboardNo commentary. No spin. Just structured data about how officials actually vote.
Incumbents are scored from actual congressional votes. Candidates use public positions and campaign statements.
We don't tell you who's right or wrong. We show you who votes like you—you decide what matters.
Guest responses are stored without your name or email. If you create an account, responses are linked to your profile. We never sell individual data.
Incumbent matches link to actual votes. Candidate data cites public sources where available.
See exactly where you align and where you differ on each policy area. No oversimplified scores.
Every bill summary is the official Congressional Research Service text, copied word for word. Where no official summary exists we show nothing rather than a guess.
We name 8,000 officeholders — 7,439 state legislators across the 50 states, DC, and Puerto Rico, 50 governors, and 1,110 mayors (mayor rosters come from Wikidata and are not yet hand-verified) — and show the statewide races on your ballot. Only Congress has a voting record we score; for everyone else we say who holds the seat and show no match rather than a guess.
We track voting records across the issues Americans care about most.
Our methodology is transparent and our data comes from authoritative sources.
