John Braun secured a narrow plurality in Washington’s August 4 top-two primary for the 3rd Congressional District, finishing ahead of incumbent Marie Gluesenkamp Perez after final tallies showed him at roughly 39.6% to her 36.6%. His commanding market position reflects strong Republican consolidation behind the state Senate minority leader, bolstered by President Trump’s endorsement, substantial fundraising, and institutional party support that limited GOP vote fragmentation. In contrast, Democratic support split between Perez and progressive challenger Brent Hennrich, whose nearly 17% share reduced the incumbent’s total. With ballots largely counted and both candidates advancing to the November general, the implied probability of Braun finishing first rests on these verified primary outcomes; any remaining uncertainty centers on final certification or rare late adjustments.
