These figures are for Forrest Mandeville, House District No. 57, 2018. These figures follow the same rules as the public campaign finance site, because they come from it. Only filed reports count. Money a campaign moves between its own accounts is left out, because it is not new money. The contribution figure is cash, as on the state's Cash Summary, and goods and services given in kind are reported beside it, never inside it. Refunds paid back to contributors are subtracted. Other receipts are interest, rebates and similar receipts, not donations. A debt is money still owed, not money spent, and a loan repaid in full is not listed as owed.

What this record does not say about Forrest Mandeville, House District No. 57, 2018, data through 2026-10-08

It does not say whether Forrest Mandeville won. CERS records candidacies and money, not results. Contribution totals are floors, not exact figures: the same real person or business can appear in the record more than once under spelling variants, and merging those into single identities is ongoing work. A total means "at least this much".
