Washington has open presidential primaries. Voters are not asked for party affiliation when registering to vote, and are only asked for a party declaration in presidential primaries -- however, this has no bearing on how a voter may vote in future presidential primaries. For all other primaries, Washington uses a top-two primary system that allows voters to choose among all candidates running for each office. The two candidates who receive the most votes in the Primary Election qualify for the General Election. 17-year-olds cannot vote in the primary election even if they will be 18 by the corresponding general election.
