Campaign money

Method

In the 2025–26 cycle Blackburn’s campaign raised $6.2M: $493K (8%) from individuals and $265K (4%) from PACs and other committees. Cash on hand: $867K.

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.
