General election race ratings

See also: Race rating definitions and methods

Ballotpedia provides race ratings from four outlets: The Cook Political Report, Inside Elections, Sabato's Crystal Ball, and DDHQ/The Hill. Each race rating indicates if one party is perceived to have an advantage in the race and, if so, the degree of advantage:

• Safe and Solid ratings indicate that one party has a clear edge and the race is not competitive.
• Likely ratings indicate that one party has a clear edge, but an upset is possible.
• Lean ratings indicate that one party has a small edge, but the race is competitive.
• Toss-up ratings indicate that neither party has an advantage.

Race ratings are informed by a number of factors, including polling, candidate quality, and election result history in the race's district or state.

Post-filing deadline analysis

The following analysis covers all U.S. House districts up for election in Washington in 2024. Information below was calculated on June 4, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.

Sixty-two candidates ran for Washington’s 10 U.S. House districts, including 26 Democrats, 25 Republicans, three Independents, and eight non-major 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.

The 5th and 6th Congressional Districts were open in 2024, meaning no incumbents ran 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) did not run for re-election because they retired from public office.

Eleven candidates—five Democrats and six Republicans—ran for the open 5th Congressional District, the most candidates who ran for a seat in Washington in 2024.

All 10 primaries were contested in 2024. Between 2022 and 2014, an average of 9.6 primaries were contested per year.

Eight incumbents—seven Democrats and one Republican—were in contested primaries in 2024. Between 2022 and 2014, an average of 8.8 incumbents were in contested primaries per year.

No districts were guaranteed to either party because Democratic and Republican candidates filed to run in all 10 districts. 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.

Partisan Voter Index

See also: The Cook Political Report's Partisan Voter Index

Heading into the 2024 elections, based on results from the 2020 and 2016 presidential elections, the Cook Partisan Voter Index for this district was D+7. This meant that in those two presidential elections, this district's results were 7 percentage points more Democratic than the national average. This made Washington's 10th the 155th most Democratic district nationally.
