Campaign money

Method

In the 2025–26 cycle Bost’s campaign raised $1.3M: $513K (39%) from individuals and $811K (61%) from PACs and other committees. Cash on hand: $790K.

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.
