Campaign money

Method

In the 2025–26 cycle Casten’s campaign raised $2.1M: $1.3M (63%) from individuals and $724K (34%) from PACs and other committees. Cash on hand: $1.3M.

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.
