Methodology Disclosure
Dark money figures are derived from FEC Form 5 (independent expenditures by non-committee organizations) and Form 9 (electioneering communications). These filings capture spending on ads and election communications but do not reveal the identity of the organization's donors. QPQ totals may differ from benchmarks like the Brennan Center's estimates because QPQ includes all Form 5 filers, while some benchmarks count only a subset of non-disclosing nonprofits. Grant chain data is from IRS Form 990 Schedule I and may not include all years or all grantee organizations.
