The Institute for Legislative Analysis scorecard tracks limited-government principles based on substantive 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 substantive votes a lawmaker cast in alignment with ILA's position. Bills are weighted by Institute for Legislative Analysis's research team. See the methodology page for full details on 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 substantive vote. A low score means they voted against ILA's positions on most substantive votes. Lawmakers below the participation threshold are marked N/A.
