How to read this
Each bar is the current party split of the chamber: Democrats left, Republicans right, independents between. The marker is the majority threshold (51 of 100 in the Senate, 218 of 435 in the House).

How party loyalty & attendance are computed
For each recorded vote we find the majority position of a member's own party, then measure how often they voted with it (party loyalty). Attendance is votes cast vs. eligible. Computed over the most recent roll calls; refreshes daily. House figures appear once the House holds recorded votes in the window.
What Is a Congressional Scorecard?
A congressional scorecard (also called a "rating" or "grade") is a numerical score assigned to a legislator based on how they voted on a curated set of bills and amendments. Organizations across the political spectrum publish them annually: conservatives, progressives, environmentalists, gun rights advocates, and more.
Scorecards serve different purposes: donors use them to evaluate giving priorities, advocacy groups use them to mobilize members, and voters use them to quickly assess alignment. They are inherently perspective-driven; each organization selects votes that reflect its own policy priorities, so a 100% rating from one group and a 0% from another tells you as much about the organizations as it does about the legislator.
How to read a score: Most scorecards are expressed as a 0–100 percentage. A score of 100 means the legislator voted with that organization on every tracked vote. A score of 0 means they never did. Scores near 50 often indicate a moderate or split-ticket approach to that issue set. Always check the methodology; some organizations track only 5–10 votes per year; others track 30 or more.
Who Scores Congress and Why It Matters
-
ACU Ratings Conservative
American Conservative Union
The oldest continuous congressional rating system, published annually since 1971. The ACU selects 20–25 votes per chamber per year covering fiscal policy, social issues, national security, and regulatory reform. A score of 80+ is generally considered a "true conservative." Members with lifetime ACU scores above 90 earn the "Award for Conservative Excellence."
-
Heritage Action Conservative
Heritage Action for America
The activist arm of The Heritage Foundation. Heritage Action tracks a broader set of votes (typically 30–50 per year) covering procedural votes, amendments, and final passage. It also penalizes members for missed votes and for supporting "key liberal priorities." Widely used by Tea Party and MAGA-aligned donors.
-
National Environmental Scorecard Progressive
League of Conservation Voters
The LCV has tracked environmental voting records since 1970. Their scorecard covers climate, clean energy, public lands, clean water, and species protection votes. Scores above 70 earn the "LCV Environmental Champion" designation. Members who score 0–10 are named to the LCV's "Dirty Dozen" campaign targets.
-
FreedomWorks Scorecard Conservative/Libertarian
FreedomWorks Foundation
FreedomWorks emphasizes limited government, free markets, and individual liberty. It often diverges from the ACU on defense spending and foreign interventionism. Members who score high with FreedomWorks but low with ACU typically hold libertarian rather than traditional conservative positions.
-
ADA Trust Score Progressive
Americans for Democratic Action
One of the oldest liberal ratings systems, published since 1947. The ADA selects 20 key votes per year spanning labor, civil rights, healthcare, and economic equity. A score above 80 is considered strongly progressive. The ADA score is frequently used in academic political science research as a standard ideology measure.
-
GovTrack Ideology Score Nonpartisan
GovTrack.us
GovTrack uses a nonpartisan algorithm to place members on a left-right ideological spectrum based on bill cosponsorship patterns, not curated vote lists. It also tracks leadership scores (how often a member's sponsored bills advance). An important methodological note: cosponsorship patterns do not always match floor-vote ideology.
Roll-Call Activity · Auto-Updated from Official Records
How this is computed: Unlike the advocacy-group ratings above, the cards below are generated automatically each day by Congress Vote Tracker directly from official House Clerk and Senate roll-call data, with no editorial vote selection. They summarize recent floor activity in each chamber.
House Participation

Over the most recent 29 recorded House roll-call votes: 18 passed, 11 failed, and 9 decided by a margin of 5 votes or fewer.
Senate Participation
Computed from official roll-call data
Over the most recent 31 recorded Senate roll-call votes: 25 passed, 6 failed, and 15 decided by a margin of 5 votes or fewer.
