Campaign money

Method

In the 2025–26 cycle Harshbarger’s campaign raised $1.3M: $477K (37%) from individuals and $683K (54%) from PACs and other committees. Cash on hand: $2.0M.

Through Jul 17, 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.
