Washington's 1st congressional district

Washington's 1st congressional district is a United States congressional district located in the western part of the state of Washington. It encompasses a diverse area including parts of King County and Snohomish County, stretching from the Puget Sound coastline to the Cascade Range. The district is currently represented by Democrat Suzan DelBene, who has served since 2012. It is considered a solidly Democratic seat, with a Cook Partisan Voting Index rating of D+13.

History

The district was established in 1909 following Washington's admission to the Union. Its boundaries and political character have shifted significantly over the decades, originally covering a vast area of western Washington. For much of the 20th century, it was a politically competitive district, electing members from both the Republican and Democratic parties. A major realignment occurred after the 1990 Census, when redistricting made the district more suburban and Democratic-leaning. The district's boundaries were dramatically redrawn again following the 2010 Census and a subsequent court-ordered redistricting process, which created its current configuration. This process was overseen by the bipartisan Washington State Redistricting Commission.

Geography

The district covers a significant portion of the Puget Sound region, including the northeastern suburbs of Seattle. It includes the entirety of Bothell, Kirkland, Redmond, and Shoreline, as well as parts of Bellevue and Mountlake Terrace. The district extends north into southern Snohomish County, encompassing areas like Lynnwood and Edmonds. Its western boundary is defined by the Puget Sound coastline, while its eastern edge reaches into the foothills of the Cascade Range. Major transportation corridors include Interstate 5 and Interstate 405.

Demographics

According to the 2020 U.S. Census, the district has a population of 789,088. The racial and ethnic composition is diverse: 66.5% White, 15.8% Asian, 9.8% Hispanic or Latino, 2.5% Black or African American, and 0.7% American Indian or Alaska Native. The district is highly educated, with over 50% of residents aged 25 and older holding a bachelor's degree or higher, a figure significantly above the national average. Major economic sectors include the technology industry, with many residents employed by companies like Microsoft and Google in the Eastside cities, as well as healthcare, retail, and aerospace manufacturing linked to The Boeing Company.

Recent election results

The district has been a Democratic stronghold in recent federal elections. In the 2020 presidential election, Joe Biden carried the district with over 65% of the vote, compared to about 32% for Donald Trump. In the 2022 U.S. House election, incumbent Suzan DelBene was re-elected with over 65% of the vote against Republican Vincent Cavaleri. This result was consistent with the 2020 House election, where DelBene also won by a similar margin. The district's partisan lean is reflected in its Cook Partisan Voting Index score of D+13, indicating it performs about 13 points more Democratic than the national average.
