Fact-Checking Candidate Claims: A Practical, Nonpartisan Method

What a primary source is and why it matters for verifying candidate claims

Definition of a primary source

A primary source is the original, contemporaneous material that directly records an event, statement, or official act. Examples of primary sources in political verification include campaign statements, official FEC filings, legislative transcripts, audited reports, and original datasets. The Verification Handbook emphasizes prioritizing these originals because they let reviewers see wording, dates, and context without secondary interpretation, which improves reproducibility Verification Handbook

Primary sources reduce ambiguity. A campaign statement or press release shows what was said and when. A filing at a government site shows reported totals and filing dates. When you start with the original item you limit misquoting, rounding errors, and context loss. This approach is widely recommended in newsroom guides and verification training.

Primary sources also let you preserve a trail. If an item is later edited, a timestamped capture or archival copy preserves the version you examined. That makes a later audit possible and helps readers judge whether new material changes the finding.

Why primary sources are preferred for verification

Verification guides recommend starting with primary material because it lets you compare the claim to the exact original evidence. That reduces guesswork about intent, timing, and wording and supports transparent publications that others can re-check. The Verification Handbook is a common reference for this practice and explains why originals matter for rigorous verification Verification Handbook

When you base a check on a primary source you can quote exact language, attach an archived copy, and show metadata like retrieval time. Those steps are central to a nonpartisan, auditable finding.

How to categorize candidate claims quickly

Common claim types

Sorting a claim helps you pick the right sources. Typical categories include: factual claims about events or records, numeric claims such as fundraising totals, attributed quotes, and future policy promises. Each type points to different primary sources and different verification steps.

Why classification shapes where to look

For example, an attributed quote usually points back to a campaign statement, a speech transcript, or a press release. A numeric fundraising claim points to official filings or audited datasets. Classifying first narrows your search and speeds up the check. Best-practice workflows in verification training start by labeling claim type before chasing sources Verification Handbook

Short examples help. If someone says a candidate “raised X in the quarter,” treat that as a numeric claim and search campaign finance filings. If a post quotes a candidate saying a specific policy line, find the original speech or press release to confirm exact wording and context.

A concise five-step workflow for verifying candidate claims

Step 1: Classify the claim

Label the claim as factual, numeric, attributed quote, or promise. Write a one-sentence version you will test. A clear classification prevents drifting into opinion and keeps the check focused.

Step 2: Locate primary sources

Find the original document or record that would most directly show whether the claim is true. That might be an FEC filing, a campaign statement, a transcript, or an audited dataset. Prioritizing originals is a standard recommendation in verification protocols IFCN resources

Step 3: Cross-check with independent evidence

After locating a primary source, look for independent corroboration such as government datasets, audits, or third-party records. Independent checks reduce the risk of relying on a single, possibly incomplete source.

Step 4: Preserve originals and metadata

Capture screenshots, download files, and create archived URLs so others can see the same version you used. Preservation of originals and metadata is emphasized in newsroom guidance to keep checks auditable Fact-Checking Resources and Guidance

Step 5: Contact campaign and publish a clear verdict

Attempt to contact the candidate or campaign before publishing and document any reply or non-reply. Noting campaign response is part of standard verification practice and should appear in the published finding Reuters fact-checking

Where to find authoritative primary sources for U.S. campaigns

Official government records and where to search them

Start with the official repositories that maintain original filings and records. For U.S. campaigns, the Federal Election Commission is the authoritative source for campaign finance records and candidacy filings. Use the agency’s search and filing pages to retrieve committee reports and filing dates Campaign finance data and filings. See the FEC campaign guide for congressional candidates Campaign Guide for Congressional Candidates.

Other government repositories include legislative transcript archives, court dockets, and agency data portals. These official records typically include filing metadata that shows when a document was submitted or published, a critical detail for verifying time-sensitive claims.

Campaign statements and press releases as primary material

A campaign website or an official press release is a primary source for what the campaign publicly stated and when. When verifying a quote or a stated position, find the dated statement or archived page. If the campaign later edits a page, an archived copy preserves the original wording for your check.

Legislative, court, and administrative records

For claims tied to legislative action or legal proceedings, consult official transcripts and docket entries. These records often contain verbatim testimony or rulings that directly bear on a claim and provide time-stamped context that secondary summaries may miss Reuters fact-checking

Using FEC records and official filings for finance and candidacy verification

What FEC records show and why they are authoritative

The FEC maintains original campaign finance filings and candidacy reports that report committee activity, receipts, and expenditures. For U.S. federal candidates, these filings are the authoritative primary records to cite when verifying fundraising totals or committee status Campaign finance data and filings

FEC records include filing dates and document versions. That metadata shows which quarter or reporting period the reported totals cover, which helps you align a claimed total with the official time window. Always cite the specific filing and its retrieval date when you publish a check. See relevant regulations such as 11 CFR Part 104 for reporting categories and definitions.

To check committee registration or candidacy status, consult the FEC committee listing and the relevant statements of candidacy. Those pages show committee names and filing dates that confirm whether a candidate has formally registered a committee and filed the required reports AP Fact Check

Preserving evidence: screenshots, metadata, and archival copies

Why preserving originals and metadata matters

Preserving originals and metadata makes your check auditable and reproducible. If you publish a verdict, other researchers should be able to view the same files and timestamps you used. Preservation is a standard industry practice for transparency and accountability Verification Handbook

When you capture evidence, note the URL, date and time, the tool you used to capture it, and the access method. For files, keep the original download and a copy stored in an archive location that you control.

Tools and services for archiving

Use trusted web archives and save local copies. Archive services, web capture tools, and timestamped screenshots are simple ways to keep a record. Many verification guides list archiving as an essential step to preserve the exact content and context of a primary source Fact-Checking Resources and Guidance

What metadata to record for reproducibility

Record at minimum the URL, date and time of capture, file name, capture tool, and access method. If possible, include a checksum or file size to help future auditors confirm the copy. Keeping a short source log with these fields makes a later audit straightforward.

Contacting the campaign: best practices and how to document responses

Who to contact and how to reach them

Contact the campaign’s press or communications address, or use a publicly listed email or phone number. Note the name of the person you reached and the channel you used. Attempting contact and reporting the result is standard practice in reputable verification work IFCN resources. See the site contact page for an example of a public contact listing.

How long to wait and how to log non-response

Give a reasonable window for reply based on the claim’s urgency. Many organizations wait 24 to 72 hours before publishing, but document the exact wait you used. If there is no response, note the dates and methods attempted and state the non-response clearly in your finding.

How to present campaign responses in the write-up

Quote the campaign response verbatim and attribute it to the campaign or a named spokesperson. If the campaign declines to comment, say so. Neutral attribution helps readers weigh the response without interpretation.

Cross-checking claims with independent datasets and records

Matching numeric claims to datasets

When a claim includes numbers, match it to the underlying dataset or filing that produced those numbers. Compare fields and time windows precisely; a quarter-to-quarter comparison requires matching reporting periods. Cross-checking with an independent dataset reduces the risk of relying on a single, possibly misreported value Campaign finance data and filings (consult the FEC’s guidance on recording receipts at Recording receipts guidance).

Checking audits, reports, and third-party records

Audited reports and third-party registries can corroborate or contradict a primary source. Confirm the audit date and scope before relying on an audit as independent evidence. Look for versioning information on datasets to ensure you are using the right release.

Quick reliability checks include verifying the publisher, checking for an audit or review statement, and searching for updates or corrections. These small steps help you judge whether a dataset is suitable for corroboration Fact-Checking Resources and Guidance

Common pitfalls and errors in candidate claim verification

Relying on secondary reporting without checking originals

One frequent error is treating a news summary as the original. Secondary reporting can introduce rounding, paraphrase, or context loss. To avoid this, always seek the original statement, filing, or dataset and verify the exact wording or values before concluding.

Misinterpreting financial or legislative records

Financial filings use precise fields and reporting windows. Misreading a filing’s coverage period can make totals appear inconsistent. Check filing headers and metadata to confirm what period a report covers before comparing numbers.

Ignoring context or selective quoting

Context matters. A quote pulled from a longer answer can change meaning. Always read the surrounding material and, when possible, present a short excerpt with the preserved source so readers see the context you used to reach a verdict Reuters fact-checking

A reproducible source-log template and short checklist

Fields the template should include

Use a compact source-log with these fields: claim classification, one-sentence claim, primary-source links, archived copies and metadata, campaign contact log, independent checks, and a one-sentence verdict. Keeping fields consistent makes audits and replication simple.

How to store and publish archives

Store archived copies in a durable location you control and publish links to the archived versions alongside your finding. If you cannot publish the file publicly, consider a trusted repository or a published methodology note explaining access controls.

Worked example: verifying a fundraising claim

Define the claim and what to look for

Suppose a post asserts that a candidate’s committee raised a specific amount in a quarter (for example, see Michael Carbonara’s campaign launch). Convert that into a one-line testable claim and note the reporting period you will check. A numeric claim like this points directly to FEC quarterly filings and committee reports as primary sources.

Step-by-step search in FEC records

Search the FEC for the committee name and the relevant reporting period. Open the reported quarter’s filing and verify the receipts line that matches the claimed total. Note the filing date and whether the filing was amended later. Cite the filing with its retrieval date so readers can follow your steps Campaign finance data and filings

How to preserve findings and write the verdict

Worked example: verifying a quoted policy claim

Locate the original quote or transcript

When a post attributes a policy line to a candidate, find the original campaign statement, speech transcript, or press release. Search the campaign site and credible archives for the dated source and capture it as an archived copy.

Check surrounding context and timing

Read surrounding paragraphs or sentences to see if the quoted fragment omits qualification or changes the intended meaning. Context can be decisive in understanding whether the paraphrase is fair.

Cross-check factual assertions underpinning the quote

If the quote includes a factual claim, verify the underlying fact with an independent dataset or official record. Use audited data or government records where available to test embedded numeric or factual assertions rather than relying on the quote alone Reuters fact-checking

How to write a transparent verdict and communicate uncertainty

Structure and language of a verdict

Use a standard structure: a one-line claim summary, the primary sources used, an evidence summary, and the conclusion with uncertainty language. This consistent format helps readers quickly evaluate the basis of a finding and what remains uncertain.

How to note and quantify uncertainty

If data are incomplete, state what is missing and how that affects confidence. Use phrasing like “evidence suggests,” “available filings show,” or “we could not find” rather than absolute claims. This avoids overclaiming and helps readers understand limits.

How to list sources clearly for readers

List primary sources with archived links and the capture metadata. Show campaign responses in full and link to original filings or statements so readers can verify the same records you used. Clear sourcing is essential for nonpartisan accountability IFCN resources
