Washington State Political Disclosure Reports Index

Washington State's Public Disclosure Commission provides an index of imaged political finance reports and documents. The dataset includes disclosure reports for the last 10 years, covering filings from candidates, political committees, and lobbyists. It serves as a searchable record linking to original documents for verification.

Use Cases

• Analyze filing frequency and methods over time using the `receipt_date`, `processed_date`, and `filing_method` columns.
• Track candidate and committee activity by legislative district using the `legislative_district`, `office`, and `filer_name` fields.
• Identify amended reports by parsing the `origin` field for the term 'AMENDED' and cross-referencing `report_number`.
• Study document types and descriptions across election cycles using the `type`, `document_description`, and `election_year` columns.

Strengths

• Index covers a 10-year period for most political disclosure reports.
• Provides direct links to source documents via the `url` column for verification.

Limitations

• Lobbyist L1, L2, and L3 reports are incomplete after 2015, with only partial records for 2016.
• No explicit column indicates if a document has been superseded by an amendment, requiring manual review.
• The dataset may contain incomplete or incorrect information as noted by the provider.
