“Agrees with you” compares your recorded position on a bill against this member's vote on the bill's decisive roll call — passage or an equivalent up-or-down vote, not procedural motions. Abstentions are excluded rather than counted as disagreement.

Individual money routed through organizations

not the organization's own money

This 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.

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.

That's state, not district. ZIP codes straddle congressional districts, so placing a donation inside one would be a guess — and this site doesn't guess. For a House member, treat the out-of-state figure as a floor: some of the in-state money came from outside the district too.

Where their donors work

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 $324k given in amounts under $200, which never appears in the bulk download because donors under that threshold aren't named. Source: FEC ↗

When a donor said what it wanted

46 bills
48%

Voted with donors

22 of 46

Across 46 bills where an organization that gave Thompson money publicly stated what it wanted, and Thompson cast a recorded vote. Those organizations gave $527k in total.

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.

Did they keep their word?

stated position vs. recorded vote

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.
