This summary compares the current repository's OpenFEC-derived non-memo individual donor layers for Eileen Laubacher and Jessica Killin. The main finding is that the campaigns share only a small exact-name donor overlap set, while their broader fundraising patterns differ sharply in scale, geography, and typical contribution size.
The strongest source in this pass is a newly derived comparison package built from the repo's existing normalized OpenFEC Schedule A datasets for EILEEN FOR COLORADO and KILLIN FOR COLORADO. The comparison is intentionally narrow: it uses only non-memo individual donor rows and preserves exact normalized-name matches without attempting aggressive person resolution. Later live OpenFEC refreshes advanced both campaigns to APRIL QUARTERLY 2026, so this comparison should be treated as a retained line-item comparison for the earlier Schedule A layers rather than a complete donor comparison through the latest aggregate report.
3,884 unique normalized donor names for Laubacher's non-memo individual subset and 630 for Killin's equivalent subset.21 names, with 18 of those also sharing the same state field.5 overlaps rise above generic same-name matching by sharing same-state geography plus a non-generic employer or occupation signal:
