Individual money routed through organizations
not the organization's own moneyThis is individuals' money, not the organization's. Supporters write checks earmarked for a named candidate, the organization collects them and passes them on — so it isn't bound by the PAC limits above, and it doesn't come out of the organization's own funds. It is still worth knowing: somebody chose this candidate and did the gathering.
- Mortgage Bankers AssociationMORTGAGE BANKERS ASSOCIATION POLITICAL ACTION COMMITTEE (MORPAC)$21k
- RoundsTHE PETER NORBECK LEADERSHIP PAC$11k
A PAC can give a candidate up to $10,000 per election cycle — $5,000 for the primary and $5,000 for the general — so totals spanning two cycles run to about $20,000 at the top end. Occasional larger figures usually mean a special election or a runoff, which counts as another election.
Money moved between committees the candidate controls — a House campaign fund transferred to a Senate run, for instance. It isn't a donation from anyone and isn't counted as one.
The PAC figures above are the organizations' own contributions only. Earmarked money they merely carried is listed separately, and independent expenditures separately again — they aren't gifts to the campaign, and money spent against a member would otherwise appear as backing.

Grouped from what donors wrote in the employer box on their own filing. It's free text, so “retired”, “self” and “homemaker” are dropped rather than dressed up as employers — and one employer can appear twice under two spellings, because merging them would mean guessing which spellings mean the same thing. A company listed here has given nothing itself; its employees have, as individuals.

Name and state only — no address, no employer, and no way to search for a person on this site. These are public FEC filings, but someone who gave $3,500 is a private citizen, not a public official, and the point of listing them is to show who funds a politician rather than to build a directory of donors.
Individual giving is aggregated by the FEC and read from its API — including the $1.6M given in amounts under $200, which never appears in the bulk download because donors under that threshold aren't named. Source: FEC ↗

Read this carefully: it counts only bills where the organization itself stated a position, in its own lobbying filing or a public statement, and where the member cast a recorded vote. VoteWire never guesses what a donor wanted. And alignment is not influence — PACs overwhelmingly give to members who already vote their way, so a high number more often reflects who chose whom than who bought whom. The full method.

Fair warning on reading this section: a bill can change a great deal between the day a member adds their name to it and the day it reaches the floor. Voting against a bill you cosponsored is sometimes a reversal and sometimes a reasonable response to an amendment — which is why every row links to the official record instead of just handing you a verdict.
