Who has a stake in Collins

The organizations behind the money.

Collins's largest organized backing comes from Votesane PAC. That counts the group's own PAC check plus the individual donations it bundled, not just the direct check.

$3.2M in PAC money not itemized by group

Collins collected $3.2M of PAC money through a joint fundraising committee, which pools contributions and transfers them as a lump sum. It is counted in the organized total above, but FEC filings do not itemize which PACs it came from at the campaign level, so it is not attributed to a named organization here.

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. Collinsreceived so many small earmarked donations that these figures count only the largest ones. Read every total as “at least.”

The same money, by industry

The money spent about Collins

Spent for or against.

Outside groups also spend on their own to elect or defeat Collins, running ads for or against the race. This money never passes through the campaign, so it is counted apart from the money organized for Collins.

About this data

FEC-disclosed receipts for the 2015–2020 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.

84%want dark money disclosed

Support for requiring the groups that spend on elections to name their donors, across both parties. Congress has not passed the DISCLOSE Act.
