Lobbying

The other way to buy a vote

Campaign money gets a politician elected. Lobbying money tells them what to do once they are there. Every lobbyist has to file with the Senate four times a year saying who paid them, how much, and which bills they worked. This section follows 68 of the biggest clients in the industries this site tracks, 2021–2026, and the lobbying behind every key vote on the Issues pages.

Pharma and health care outspent everyone, $523M across 5 companies and trade groups. Compare that with what the same industry gave to candidates and super PACs on the Industries page: lobbying is usually the bigger number, and it never shows up in a campaign finance report.

Source: Senate Lobbying Disclosure Act filings (lda.gov REST API)Lobbyists' covered positions, from Senate LDA filings. Spend is the amount on each quarterly report (a firm's income from the client, or an in-house registrant's expenses), latest amendment only. Clients are matched by name, so subsidiaries filing separately are not included. Covered positions are as the lobbyists wrote them. See About the data.
