What a committee is

Money in federal politics flows through committees— not through candidates directly. A committee is a registered entity (Form 1 filed with the FEC) with a treasurer, an address, a bank account, and an FEC committee id like C00580100.

The committee type field in FEC data uses single-letter codes (P, H, S, N, Q, O, X, U, V, W, Y, Z); designation uses another single letter (P, A, J, D, U, B). The taxonomy below maps the policy categories onto those codes.

Candidate committees

Political action committees (PACs)

Super PACs + hybrid PACs

Joint fundraising committees (JFCs)

Party committees

Adjacent entities (not technically PACs but in the data)
