In Detail
When tracking politicians in the United States, finding objective, reliable data requires looking at specific non-partisan databases, government repositories, and investigative journalism outlets.
Here is a breakdown of the best sources for each parameter, categorized by what they do best:
1. Accountability (Ethics, Finance, & Fact-Checking)
Tracking campaign money, special interest influence, and truthfulness.
- OpenSecrets (Center for Responsive Politics): The gold standard for tracking "follow the money" data. It maps campaign contributions, super PAC spending, lobbying data, and politicians' personal financial disclosures.
- FactCheck.org & PolitiFact: Non-partisan projects that monitor the factual accuracy of what US politicians say in speeches, TV ads, and interviews. PolitiFact features the "Truth-O-Meter" and tracks the fulfillment of campaign promises (e.g., the Biden Promise Tracker).
- Federal Election Commission (FEC): The official government database (
fec.gov) where all federal candidates must file financial reports. It is raw data, but completely authoritative for official compliance.
2. Performance of the Position Occupied
How active they are in their legislative or executive role.
- GovTrack: Excellent for tracking a lawmaker's legislative activity. It provides a "Legislative Report Card" for every member of Congress, showing how many bills they sponsor, how often they get bills out of committee, and their missed vote rates.
- Congress.gov: The official database of the US Congress. It lets you look up a politician to see every bill they have sponsored or co-sponsored, their committee assignments, and speech transcripts from the Congressional Record.
3. Transparency
Accessibility, public records, and meeting tracking.
- ProPublica: An independent, non-profit newsroom that produces investigative journalism in the public interest. Tools like their Represent database track how often lawmakers vote against their own party, switch votes, or miss votes entirely.
- Ballotpedia: A massive digital encyclopedia of American politics. It tracks candidate backgrounds, official statements, and transparency metrics at federal, state, and local levels.
- State-Level Portals: For politicians outside Washington D.C., transparency data depends on state laws (like FOIA or Sunshine laws). Open States (
openstates.org) is a great tool for tracking the transparency and activity of state-level legislators.
4. Public Sentiments
How the electorate perceives a politician in real-time.
- FiveThirtyEight (538) / ABC News: Aggregates and weights political polling from dozens of distinct sources. They maintain continuous, historically tracked approval rating charts for the President, key governors, and high-profile senators.
- RealClearPolitics (RCP): A polling aggregator that provides a running average of major public opinion polls regarding approval ratings, upcoming election matchups, and direction-of-country metrics.
- Roper Center for Public Opinion Research: For deep historical context, this archive (housed at Cornell University) holds the largest collection of public opinion data in the world.
5. Political Stance (Voting Records & Ideology)
Where they stand on issues and how they vote when it counts.
- Vote Smart: Their "Votes Easy" tool is one of the best ways to see a politician's stance. They issue non-partisan "Political Courage Tests" and collect voting records, public statements, and ratings from various special interest groups across the political spectrum.
- The Lugar Center - McCourt School Bipartisanship Index: Measures how frequently a member of Congress co-sponsors bills with members of the opposite party, helping identify where they sit on the ideological spectrum (partisan vs. moderate).
- Voteview (UCLA): A highly academic, data-driven platform that maps the ideological positions of every member of Congress over time using their entire voting history, placing them on a clear Left-to-Right economic and social scale.
A Quick Tip on Special Interest Group "Scorecards": Organizations like the ACLU, the NRA, or the Sierra Club issue "scores" (0-100%) for politicians based on how they vote. While useful to see a politician's stance, remember these scores are inherently biased toward that group's specific agenda. It is always best to cross-reference them with raw voting data from GovTrack or Congress.gov.
