Method

In the 2025–26 cycle Lummis’s campaign raised $3.0M: $805K (27%) from individuals and $1.4M (47%) from PACs and other committees. Cash on hand: $1.7M.

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.
