Bầu cử tổng thống Hoa Kỳ tại Washington năm 2024

The 2024 United States presidential election in Washington took place on Tuesday, November 5, 2024, as part of the 2024 United States presidential election in which all 50 states plus the District of Columbia participated. Washington voters chose electors to represent them in the Electoral College via a popular vote. It was held along a gubernatorial and U.S. Senate election. The state of Washington has 12 electoral votes in the Electoral College, following reapportionment due to the 2020 United States census in which the state neither gained nor lost a seat.

Although Washington was a Republican-leaning swing state until the 1980s, Democrats have won Washington in every presidential election starting in 1988 and have consistently done so by double digits since 2008. Washington is part of the Democratic-leaning West Coast and was predicted to go comfortably to the Democratic Party in 2024.

As expected, Kamala Harris comfortably won Washington state. While Trump improved his margin in all fifty states, Washington had the smallest swing to the right, with Trump improving his margin by 0.98%, compared to the national swing of about 6%. After Biden's 19% margin of victory in 2020, Harris' 18% margin was the second-largest in the state for the Democratic Party since 1964.

Some of the few counties in the country to swing significantly leftward were in Washington, including Clallam, Island, Jefferson, and Kitsap counties, where Harris had some of the best Democratic performances in their history. In the former bellwether Clallam County, Harris had the best performance for any candidate since 1984, and the best for any Democrat since 1964. This ended Clallam County's 40-year bellwether streak from 1980 to 2020, as the county had not voted for the losing presidential candidate since 1976.

Harris also outperformed Democratic gubernatorial nominee Bob Ferguson in the concurrent gubernatorial election. Ferguson won the governorship by 11.23 percentage points, while Harris carried Washington by 18.22 points. However, Harris slightly underperformed Maria Cantwell, who won by 18.45% in the concurrent senate election.
