Four candidates are on the ballot for Washington state's Republican presidential primary, which is being held on Tuesday, March 10, 2026. The contest is a key step in the process of allocating the state's delegates to the Republican National Convention later this year.
The candidates listed for voters include the incumbent Republican president, Donald J. Trump, who is seeking re-election. He is challenged by former South Carolina Governor Nikki Haley, entrepreneur Vivek Ramaswamy, and Florida Governor Ron DeSantis. This primary follows the "Super Tuesday" contests held earlier in March.
Washington's primary is a hybrid system. While the Democratic primary is open to all voters, the Republican primary is partially closed, allowing only voters who declare a Republican affiliation to participate. The state awards its delegates on a proportional basis, meaning multiple candidates could earn a share based on their performance statewide and within congressional districts.
The outcome is widely anticipated to influence the remaining primary calendar as candidates seek to secure the 1,215 delegates needed to clinch the Republican nomination. As of the primary date, former President Trump holds a significant lead in the national delegate count following strong performances in earlier state contests.
