Campaign money

Method

In the 2025–26 cycle Mast’s campaign raised $4.3M: $3.2M (74%) from individuals and $389K (9%) from PACs and other committees. Cash on hand: $2.9M.

Through Jul 29, 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.
