In Washington, a voter is not required to register by political party or declare party membership to vote in any election.

During the Primary in even-numbered years, voters elect Precinct Committee Officers to be their grassroots political party precinct representatives.

Specific questions regarding political party activities should be directed to the political party headquarters.
