Washington state's top-two primary for the 3rd Congressional District on August 4, 2026, features incumbent Democrat Marie Gluesenkamp Perez facing eight challengers, including Republican state Senate Minority Leader John Braun and Democratic candidate Brent Hennrich. Perez maintains a substantial fundraising edge exceeding $2 million in cash on hand, while Braun represents the primary Republican threat in the swing district. Multiple candidates from the left, right, and center have filed, splitting the vote and raising the possibility that the top two finishers will determine general election matchups. The filing deadline passed in May with no major late developments reported in the final weeks before voting.
