## What this record does not say about Andrea Olsen, House District No. 100, 2018, data through 2026-09-30

It does not say whether Andrea Olsen 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".
