Ballots need to be postmarked by today (Tuesday) in the Washington state primary election. Washington uses a top-two primary system, in which the top two vote getters in the primaries advance to November’s general election, regardless of party affiliation. Locally, County Commission races only have two candidates except for Skamania County District 2, with seven people seeking to advance to the general election. A number of area state legislative races have three candidates. Most statewide and Congressional positions have a large number of candidates seeking to advance.
