PAS — Platform Alignment Score
Challengers only
For challengers without a voting record, the Platform Alignment Score measures how closely their stated positions align with majority opinion on each pillar. The
Endorsement-Adjusted Score applies a correction based on who is backing them — because endorsements predict votes more reliably than campaign promises. A gap between stated and adjusted scores is the endorsement gap.
Endorsement gap example: A challenger states they support lower drug prices (high Healthcare pillar) but takes PhRMA PAC money. Their endorsement-adjusted score is lower — reflecting what their donors predict they will actually vote for.
MAS — Majority Alignment Score
0 – 100
Measures how closely an incumbent’s voting record aligns with documented majority opinion across all four pillars. Every tracked vote has a verified majority position from polling (60%+ threshold). A score of 100 means the incumbent voted with the majority on every tracked issue. A score of 0 means they voted against the majority on every tracked issue.
ECON — Economic Impact Score
0 – 100
Measures the economic consequence of an incumbent’s voting record across three dimensions. Votes are weighted by their direct dollar impact on American workers, businesses, and global competitiveness.
GDP & Jobs — Votes affecting workforce size, business formation, energy costs, and economic output
Fiscal Impact — Votes affecting the deficit, drug prices, Social Security solvency, and government spending efficiency
vs. China Competitiveness — Votes affecting America’s position in STEM, clean energy, shipbuilding, and critical minerals
What counts as a “Majority Position”?
A majority position is any policy stance supported by 60% or more of Americans in verified national polling. TheMajority.us uses data from HarrisX, YouGov, Gallup, Quinnipiac, and Pew Research. The majority position on each tracked vote is publicly sourced and updated quarterly. If polling on an issue shifts below 60%, that vote is reclassified or removed from the pillar score.
Example: 74% of Americans support Medicare drug price negotiation (KFF, 2025). Any vote against this bill counts as a vote against the majority position on the Healthcare pillar.
Pillar Scores (Energy, Healthcare, Education, Immigration)
Each of the four pillars is scored 0–100 based on votes in that specific policy area where majority opinion is documented. The MAS is the weighted average of all four pillar scores, currently weighted equally at 25% each. Pillar weights may be adjusted to reflect the policy priorities of the 2026 election cycle.
Favorable Rating
The percentage of constituents in the incumbent’s state or district who view them favorably, based on the most recent publicly available polling. Sources include Morning Consult Senate Approval Ratings, Quinnipiac, YouGov, and state-level polling organizations. Ratings are updated as new polls are published.
Note: Favorability reflects how voters feel about an incumbent. The MAS reflects what they actually vote for. The gap between the two is where TheMajority.us does its most important work.
Party-Line Rate
The percentage of votes where an incumbent voted with their party’s majority. A 99% party-line rate means the incumbent voted with their party on 99% of all votes — regardless of what their constituents support. Source: CQ Roll Call party unity scores, updated quarterly.
LCV Score
The League of Conservation Voters lifetime score, measuring an incumbent’s voting record on environment and energy legislation. Used as the anchor data point for the Energy & Environment pillar score. A score of 100% means the incumbent voted for the environment on every tracked LCV vote. A score of 0% means they voted against on every tracked vote.
