Washington State Candidate and Committee Expenditures for the Last 10 Years

Ten years of expenditures made by Washington State candidates and political committees, as reported to the Public Disclosure Commission (PDC). The data includes in-kind contributions and is sourced from forms C3, C4, Schedule C, and their electronic equivalents. The dataset is provided by the State of Washington as a best-effort record and was last updated in March 2026.

Use Cases

• Analyzing spending trends over election cycles based on the 10-year time range.
• Tracking in-kind contributions to political campaigns as described in the data.
• Comparing expenditure patterns between candidates and political committees.
• Verifying campaign finance reports against original PDC filings for compliance checks.

Strengths

• Covers a 10-year time period for longitudinal analysis.

Limitations
