How to Read Campaign Finance Data Without Misreading the Totals

Start with the filing and reporting period

Use the FEC campaign finance data portal to locate a candidate or committee and review receipts, spending, filings, loans, and debts. Confirm which committee, form, and reporting period you are viewing before comparing figures. Candidate summaries can include total receipts, disbursements, contributions, cash on hand, and debts, but those categories describe different parts of a campaign’s finances. The FEC candidate research guide also distinguishes authorized campaign reports from outside committees’ independent expenditures and communication costs.

Know what individual contributions show

An individual-contribution record can include the donor name, occupation and employer, city and state, date, amount, and reporting committee. Use the FEC individual-contribution search to filter those fields. Treat the employer field as reported information about the individual; it does not establish that the employer made the contribution.

Read filings before relying on a total

The FEC filings search lets you search reports and statements by committee or filer, date, and form. Review the underlying filing and its methodology when reporting a specific amount. Adjusted totals and raw receipts or disbursements may use different rules, and newly filed summary data may take time to appear.

Be especially careful with broader candidate files. The FEC all-candidates file description notes that a financial summary may double-count activity when it combines a candidate’s authorized committees, including transfers between those committees. Reporting periods may also vary between candidates. Do not combine figures from different periods or datasets without checking how each total was calculated.

Independent-expenditure data requires its own check. The FEC independent-expenditures file description explains that the bulk file contains transactions from original and amended reports. Raw rows can therefore inflate a sum if amendment and report identifiers are not examined alongside the underlying filing.

Take the next step

For a specific candidate, begin with the FEC portal, record the committee and reporting period, then open the relevant filing before drawing a comparison.
