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 Dru Koester

It does not say whether Dru Koester won any of these elections. 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".
