Campaign money

Method

In the 2025–26 cycle Collins’s campaign raised $16.2M: $10.5M (65%) from individuals and $1.2M (7%) from PACs and other committees. Cash on hand: $11.0M.

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.
