This year’s filing deadline for candidates running for Congress in Washington was May 10, 2024.

Sixty-two candidates are running for Washington’s 10 U.S. House districts, including 26 Democrats, 25 Republicans, three Independents, and eight minor-party candidates. That’s an average of 6.2 candidates per district. That’s lower than the 6.8 candidates per district in 2022 and the 7.3 in 2020.

Here are some other highlights from this year’s filings:

• The 5th and 6th Congressional Districts are open this year, meaning no incumbents are running for re-election. That’s the most open districts in an election cycle this decade.

• Incumbent Reps. Cathy McMorris Rogers (R-05) and Derek Kilmer (D-06) are not running for re-election because they are retiring from public office.
• Eleven candidates—five Democrats and six Republicans—are running for the open 5th Congressional District, the most candidates running for a seat in Washington this year.
• All 10 primaries are contested this year. Between 2022 and 2014, an average of 9.6 primaries were contested per year.
• Eight incumbents—seven Democrats and one Republican—are in contested primaries this year. Between 2022 and 2014, an average of 8.8 incumbents were in contested primaries per year.
• No districts are guaranteed to either party because Democratic and Republican candidates filed to run in the primaries in all 10 districts.

Washington and three other states—Kansas, Michigan, and Missouri—are holding primary elections on August 6, 2024.

Washington utilizes a top-two primary system. In a top-two primary system, all candidates are listed on the same ballot. The top two vote-getters, regardless of their partisan affiliations, advance to the general election.
