Federal data guide

Money, Politics & Government Spending Data

A guide to the federal datasets that follow money through American politics and government — who funds campaigns, who pays to lobby, where the government spends its trillions, and how members of Congress vote and trade. Each links to a full deep-dive, and the cross-dataset analysis joins them.

Money and politics leave an unusually rich federal trail. The FEC publishes campaign contributions and the committees, PACs, and super PACs that move them; the Senate and House lobbying disclosures record who is paid to influence Washington; USAspending.gov accounts for the contracts, grants, and loans the government awards; and Congress’s own votes, research service, and stock trades are public. The hard and valuable move is joining them — connecting a donor to a contractor to a vote — which the cross-dataset guide below walks through. The guides group the deep-dives by source.
