Campaign Finance & Disclosure Information

Candidates running for Multnomah County office:
On Nov. 8, 2016, voters amended the Multnomah County Charter to include limits on campaign contributions and the amount of money that can be spent to support or oppose candidates for Multnomah County office. The measure also requires various disclosures of contributions and spending. 

On March 6, 2018, Circuit Court Judge Eric J. Bloch struck down key elements of recent Multnomah County legislation regulating campaign finance in Multnomah County candidate elections. In particular, the court concluded that the following provisions of the legislation violate the free speech clause of the Oregon Constitution:

  1. Limits on campaign contributions;
  2. Limits on campaign expenditures and independent expenditures; and
  3. A requirement to disclose certain funding sources in campaign communications

The court upheld requirements in the amendment around registering as a political committee and employees’ rights to make contributions by payroll deduction as permissible under state and federal law.

On July 18, 2019, the Multnomah County Board approved a resolution to develop an ordinance by December 31, 2019, requiring communications relating to Multnomah County candidate elections to disclose funding sources.

More information can be found by visiting the county’s website. 


City of Portland candidates have similar campaign finance and disclosure requirements. Please visit the City of Portland Elections website for more information. All questions related to City of Portland candidates should be directed to the City of Portland Elections office.

Information on City of Portland candidate public financing is available at the City of Portland website Open and Accountable Elections.
