Campaign money

Method

In the 2025–26 cycle Duckworth’s campaign raised $5.1M: $4.5M (87%) from individuals and $132K (3%) from PACs and other committees. Cash on hand: $4.1M.

Through Jun 30, 2026; filings lag, so recent gifts can take weeks to appear. Money raised also counts loans and transfers, so the shares need not add to 100%. Source: FEC.gov.
