Select a slice to explore it. Outside spending supports or opposes candidates; it does not go to their campaigns. The combined amount is not a campaign fundraising total. Each side groups money working for one candidate, shaded in that candidate's party colour; the darkest shade is the campaign's receipts, lighter shades are outside spending supporting them and opposing their opponent. Only the receipts reach the campaign; a side total is a comparison figure, not a fundraising total. Selecting a slice opens the candidate record it comes from.

How this breakdown is calculated

Preliminary. Every independent-expenditure dollar reported against a candidate in this race ($233,396,761 across both candidates, support and oppose) is weighted by the disclosed share of the spending committee's own receipts, as computed by the chain walk in chains/<committee>.json: the share of its money that traces back, through any number of committee-to-committee transfers, to a named individual on an FEC filing ($146,706,311) or to a named business or union giving from its own treasury ($23,803,253; the organization is named, its own funders are not walked). The remainder is dark — it stopped at an LLC, trust, advocacy nonprofit or unclassifiable organization whose own funding is not on file (classified by name; no IRS lookup). $532,391 was spent by Form 5 filers (organizations that are not registered committees and report no receipts); those dollars are counted as dark. $1,855,774 reached an FEC-registered committee whose receipts lie outside the loaded 2,000-committee neighborhood (or past the hop cap) and was not walked further; those dollars are counted as 'not walked' — neither disclosed nor dark — and do not raise the score. Super PAC spending is itself disclosed; this score is about the layer behind the spender, not the spender. Nothing is marked inferable in V0.

Source records

  • Campaign totals are the FEC candidate summary (all authorized committees, itemized and unitemized); top contributors and conduit totals are itemized Schedule A receipts to the principal committee.
  • Earmarked contributions (15E) are attributed to the individual, not the conduit (ActBlue/WinRed).
  • Outside spending = independent expenditures (Schedule E) supporting or opposing a candidate in this race, with 24/48-hour notices collapsed onto the periodic-report row for the same spend.
  • Independent expenditures are legally independent of the campaign and move no money to the candidate. Support/oppose is the spender's own declaration.

Money and positions are shown side by side because they are public records about the same person. Proximity is not causation; we make no claim that any contribution produced any action.
