How It Works
The Influence Pipeline
How money flows to — and through — Chuck Grassley's office.
01
The Company
A corporation wants a law passed or blocked.
02
The PAC
Direct donations are illegal. So employees pool money into a Political Action Committee.
03
The Target
PACs fund members on committees that regulate their industry.
04
⚖️
The Committee
These committees write the laws that affect the donor's business.
07
🗳️
The Vote
Your representative votes — and the pattern is clear.
06
📋
The Lobbying
Those lobbyists push specific bills before their former colleagues.
05
🚪
The Revolving Door
Former staff become lobbyists for the same industries that fund their old boss.
The cycle repeats.

Deep Dive
How we built this & what it doesn't prove
- • Donor data from FEC filings (9.47M individual contributions)
- • Voting records from Congress.gov roll call data
- • Lobbying data from Senate LDA filings
- • Staff employment from House disbursement records
Correlation between donations and votes does not prove causation. Members may vote in alignment with donors because they share genuine policy beliefs, not because of financial influence. We present the connections — you decide what they mean.
