The Institute for Legislative Analysis scorecard tracks limited-government principles based on key votes cast by members of Congress and state legislators. Each lawmaker receives a score reflecting how often they voted in alignment with these positions.

Scores are calculated as the percentage of weighted key votes a lawmaker cast in alignment with ILA's position. Bills are selected and weighted by Institute for Legislative Analysis's research team. See the methodology page for full details on vote selection, weighting, and the participation threshold for receiving a finalized rating.

A high score (90%+) means a lawmaker voted in alignment with ILA's positions on nearly every key vote. A low score means they voted against ILA's positions on most key votes. Lawmakers below the participation threshold are marked N/A.

Use the state and year filters above to narrow the leaderboard, or search by name. Each lawmaker's row links to their full profile, including a year-by-year voting record, category breakdown, and the key bills they were scored on.

Institute for Legislative Analysis adds new scored votes as legislative sessions progress. Each lawmaker profile shows the most recent year of available data, with lifetime ratings spanning every year they have been tracked.
