Description
Washington State's Public Disclosure Commission provides a list of all campaign finance reports, including C3, C4, C5, C6, and LMC forms, filed over the last 10 years. The dataset tracks report amendments and filing history for candidates and political committees, with the reporting period determined by election year or calendar year. It is intended for examining reporting timelines and amendment sequences.
Use Cases
Track the amendment history of C3, C4, C5, C6, and LMC reports to identify superseded filings for a specific filer.
Analyze reporting timelines for political committees by examining the calendar year of their reporting periods.
Examine candidate filing patterns by correlating reports with the year of their election, not the filing date.
