OLYMPIA, Wash. (AP) — The top two candidates for a U.S. Senate seat, 10 congressional races and the secretary of state’s office will be decided by Washington voters in Tuesday’s primary. Voters will also weigh in on dozens of legislative contests and local elections. While voters began receiving their state primary ballots in the mail weeks ago, Tuesday is the last day for voters to get them in or postmarked for mail delivery. In some of the more competitive races, results may not be known for days as most counties will update vote counts only once a day.
