Seed Data (Placeholder) — 0 states
show population-weighted estimates. These are clearly labeled and will be replaced as real data becomes available.
Raw CSVs are streamed through a normalization pipeline that maps each state's column names to a common schema (contributor, amount, date, recipient, party, office). The pipeline supports 15+ alias arrays covering variations like "ContributorName", "donor_name", "CTRIB_NAML", etc.
Contributor names are normalized: "LAST, FIRST" is reversed to "FIRST LAST", common suffixes (Jr, Sr, Inc, LLC, etc.) are stripped, and whitespace is collapsed.
Entities are classified into individual, committee, organization, or government using ~50 keyword patterns applied to name strings.
Amendment deduplication: For states with amendment tracking (e.g., California), only the latest amendment per filing is kept. CA's 19M raw records reduce to 13.2M after dedup.
Aggregate/placeholder entries ("Aggregate Donations Under $100", "Unitemized", etc.) are excluded from top-N rankings but their dollar amounts still count toward state totals.
