What to know about the Aug. 2 primary election in Washington

What's happening: King County voters are being asked to weigh in on four U.S. House seats, including the competitive race for the 8th Congressional District, east of Seattle.

• U.S. Sen. Patty Murray is also up for re-election and faces 17 challengers.
• Plus, there's a crowded race to decide who will oversee Washington's elections, with eight candidates competing for the office of secretary of state.
• All state House seats and half of state Senate seats are up for election, too. That includes more than 40 legislative seats in King County.

What's next: The Aug. 2 primary will whittle the pool of candidates in each race down to two.

• The top two vote-getters in each race will advance to the Nov. 8 general election, regardless of their party affiliation.
• Washington doesn't have party registration, so you don't need to pick a party to vote.
