Method

In the 2025–26 cycle Ernst’s campaign raised $2.0M: $997K (50%) from individuals and $637K (32%) from PACs and other committees. Cash on hand: $1.9M.

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.
