About these numbers

  • Outside spending is money groups spent on their own ads, mail and canvassing for or against a candidate. Groups can’t coordinate it with campaigns, and it isn’t counted in what campaigns raised or spent.
  • Every group that reported independent spending to the FEC is listed, not only the groups on our issue pages. Groups tracked on an issue page carry a tag linking to it.
  • Primary, special or general comes from the election the group listed on each expenditure. Seats with a special election this cycle show that money separately.
  • Late reports are 24- and 48-hour filings made since a group’s last regular report. Earlier ones are already counted on that report, so we don’t count them twice.
  • Some nonprofits don’t have to name their donors, so this shows who spent the money, not always who gave it.

FEC data as of Oct. 5, 2026. Campaign figures cover the full 2026 cycle. Current senators: Sen. Jerry Moran, Sen. Roger Marshall. How this works.
