Incumbent Democrat Judy Chu faces Republican April Verlato in California's 28th congressional district, a seat rated solidly Democratic with a partisan lean that has produced consistent double-digit Democratic margins in recent cycles. Partial vote counts on election night showed Chu leading by roughly 39-40 points, aligning closely with pre-election forecasts projecting a 35-45 point Democratic victory based on turnout patterns and district fundamentals. The absence of competitive polling or late-breaking campaign events has kept trader focus on historical benchmarks and the top-two primary outcome, where Chu advanced comfortably. With final certification pending, the 35-40% margin bin reflects the current consensus from early returns and structural factors, while wider bins capture remaining uncertainty in vote processing across Los Angeles and San Bernardino counties.
