About this data
FEC-disclosed receipts for the 2023–2024 cycle. This is the disclosed money only. Spending by outside groups that do not reveal their donors, the dark money that set a record in 2024, never appears in these figures.
Every percentage here is a share of all receipts, not of individual contributions only. So the small-donor share counts transfers, loans, and other money in its base, and can read higher than figures that divide only by individual money.
PAC figures are contributions to Castro's campaign committee from FEC filings. Industry labels are grouped from each committee's name and are approximate. Joint fundraising committees and small-dollar conduits like ActBlue and WinRed are not counted.
Support for requiring the groups that spend on elections to name their donors, across both parties. Congress has not passed the DISCLOSE Act.
