Who Actually Funds US Politicians? Data from 1990 to 2026

In this visualization I track the cumulative political contributions of America's largest individual donors across U.S. presidential and midterm election cycles from 1990 to 2026. Methodology & Data Sources: The dataset combines direct campaign donations and independently financed political spending. Contributions made through affiliated business entities and nonprofit organizations are attributed to individual donors where ownership and funding can be verified. Labor unions, PAC and Super PAC funding are excluded. The historical data is primarily based on Federal Election Commission (FEC) records, OpenSecrets databases and supplementary campaign finance reporting from ProPublica. Figures for the 2026 midterms incorporate the latest available FEC disclosures and independent expenditure reports and remain preliminary. ***** Hi, I'm Sasha.
