Incumbent Democrat Judy Chu faces Republican April Verlato in the November 3 general election for California's 28th congressional district, a seat with a D+15 Partisan Voter Index that has favored Democrats in recent cycles. The top-two primary in June advanced these two candidates after Chu captured roughly 62 percent of the vote. Forecasters rate the contest solid or safe Democratic, reflecting the incumbent's established support and the district's partisan lean. Trader pricing on margin outcomes shows the race remaining competitive in assessment, with Republican win probabilities near 37 percent and various Democratic victory ranges clustered around similar levels. Limited recent campaign events or polling shifts have sustained this equilibrium, while factors such as turnout differentials between Los Angeles and San Bernardino County portions of the district, early voting patterns, and any final-week developments could alter the exact margin distribution.
