How to See Who Funds a Politician: FEC.gov, OpenSecrets, and State Filings

A mailer hits your door and you wonder who paid for it. The answer is a free public record. Here is how to read donations and PACs without spin.

A glossy mailer hits your mailbox, or an ad interrupts your video, and a small line at the bottom says "Paid for by" some committee you have never heard of. The feeling is familiar: someone is spending real money to change your vote, and you have no idea who. The good news is that in the United States, most of that money leaves a public trail by law. You do not have to trust a pundit's summary. You can pull the records yourself, for free, and read them with your own eyes.

This is the core of how NU works: rank by the record, not by who shouts loudest. Here is how to trace political money to its source and read it honestly.

Start at the source: FEC.gov for federal races

Anyone running for President, U.S. Senate, or U.S. House files with the Federal Election Commission. Their disclosure site, fec.gov, is the primary record. The aggregators you have heard of are mostly reselling and repackaging this same free data.

Go to fec.gov and use the search bar for a candidate or committee name. A candidate page shows total raised, total spent, and cash on hand, plus links to every filed report. Two views matter most:

• Receipts lists who gave money. Individual donors who give over $200 in a cycle must be itemized with name, city, employer, and occupation. That employer-and-occupation field is the part people skip and the part that tells you the most about whose interests are in play.
• Disbursements lists where the money went: ad buys, consultants, payroll, travel.

Use fec.gov's "Browse data" tools to filter individual contributions by donor name, employer, or ZIP code. You can literally check whether your neighbor, a local company, or an out-of-state industry is funding a race in your town.

OpenSecrets and FollowTheMoney for the readable summary

Raw FEC files are accurate but clunky. OpenSecrets.org (run by the nonprofit OpenSecrets) takes the same federal data and organizes it into plain-language profiles: top contributors, top industries, PAC versus small-donor breakdowns, and how much comes from inside versus outside a candidate's district or state. It is the fastest way to see patterns.

For state and local races, OpenSecrets' sister resource FollowTheMoney.org (the National Institute on Money in Politics) is the standout. It pulls together filings from all 50 states, which is otherwise the hardest data to find in one place.

Treat these as interpretation layers, not gospel. They categorize donors by industry using judgment calls, and categories can mislead. When a number matters to you, click through to the underlying FEC or state filing and confirm it yourself.

Reading PACs without getting fooled

"PAC" is where most people get lost, so keep three plain distinctions:

• A traditional PAC collects limited, disclosed contributions and gives directly to candidates. Its donors are reported.
• A Super PAC can raise and spend unlimited money to support or oppose candidates, but it cannot coordinate with the campaign and cannot give to it directly. Its donors are also disclosed to the FEC.
• A 501(c)(4) "social welfare" nonprofit can spend on politics without naming its donors. This is the real source of so-called dark money. When a Super PAC's biggest "donor" is a vaguely named nonprofit, you have hit the edge of the public record. That is not a dead end to ignore. It is a finding: the trail was deliberately ended there.

So when you see a committee name on an ad, search it on fec.gov. Ask one question: does this committee disclose real human or corporate donors, or does its money arrive from another committee that does not? The answer tells you how much weight the funding deserves.

State and local filings: where it gets local and messy

Your city council, mayor, school board, and state legislators do not file with the FEC. They file with a state agency — often the Secretary of State, a state ethics commission, or a campaign finance board. Coverage is uneven and the portals vary in quality.

• Search "[your state] campaign finance disclosure" or "[your state] Secretary of State campaign finance."
• Many states have searchable databases (California's Cal-Access, New York's and Texas's state ethics portals are examples). Some smaller jurisdictions still post only PDFs you must read by hand.
• A blank or clunky result is not proof of nothing. It is proof that this portal is the place to keep looking, or to file a records request.

Read it like an investigator, not a partisan

The records are powerful, but only if you handle them honestly:

• Follow employer and occupation, not just names. Twenty people from the same company maxing out on the same day is a clearer signal than one big check.
• Watch the in-district versus out-of-district split. A local candidate funded mostly from another state or by national industry PACs is telling you who they answer to.
• Money is influence, not proof of a quid pro quo. A donation shows interest and access. It does not by itself prove a vote was bought. Say what the record shows and stop there.
• Confirm before you accuse. Common names produce false matches. Cross-check a donation against a second detail (employer, city) before you treat it as the same person.

The pattern never changes: ask "what agency is required by law to keep this record?" and go straight to it. For federal races that is fec.gov. For everything below it, that is your state's disclosure office. Read the primary filing, use OpenSecrets and FollowTheMoney to spot the pattern, and cite exactly where each fact came from. Do that, and you will understand who is funding a politician better than almost anyone repeating it back to you secondhand.
