Incumbent Pramila Jayapal advanced comfortably through the August 2026 top-two primary in Washington's 7th District, capturing over 80 percent against Republican Nirav Sheth and minor challengers in the heavily Democratic Seattle-area seat rated D+39 by partisan voter index. All major forecasters classify the November 3 general election as solid or safe Democratic, with models projecting margins near 55 points. Trader pricing reflects this baseline while spreading probability across Democrat victory buckets from 50-90 percent-plus, driven by limited recent polling, variable turnout in urban strongholds, and uncertainty over national midterm conditions that could modestly compress or expand the final margin. A Republican victory remains a low-probability outlier absent major late shifts.
