pac.dog is a free, independent, non-partisan research tool. Every candidate, committee, bill, vote, member, and nonprofit on this site is mirrored from primary U.S. government sources (FEC, congress.gov, govinfo.gov, IRS) and each state's Secretary of State / election commission — no third-party data vendors, no paywall, no editorial intermediation. Citations to the originating source are on every detail page.

Estimated value: $180/mo per user — but we made it free.
