› What is organized money?
An organization reaches a member two ways. Its own PAC writes a direct check. And it bundles: it gathers individual donations from its supporters and routes them through its conduit. Both count here as one “organized” total. The bundled part is already inside the individual giving shown in the funding mix above. Here it is regrouped by the organization that gathered it, so you can see who did the organizing. Blackburnreceived so many small earmarked donations that these figures count only the largest ones. Read every total as “at least.”
The same money, by industry
Which industries have a stake.
The same organized money, grouped by the industry of the organization that moved it. It shows the interests behind Blackburn's backing, not just the individual groups.
Plus $1.1M from organizations whose FEC name did not sort into an industry.
The money spent about Blackburn
Spent for or against.
Outside groups also spend on their own to elect or defeat Blackburn, running ads for or against the race. This money never passes through the campaign, so it is counted apart from the money organized for Blackburn.

About this data
FEC-disclosed receipts for the 2019–2024 term. 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 Blackburn'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.
