Incumbent Democrat Judy Chu advanced from the June 2026 top-two primary with 62 percent of the vote against Republican April Verlato, setting up a November 3 general election in California's 28th congressional district. The seat carries a D+14 partisan voter index based on recent presidential results, and nonpartisan ratings from Cook, Inside Elections, and Sabato classify it as solid or safe Democratic. Trader consensus at 97.8 percent Democratic reflects the district's consistent voting patterns, limited Republican infrastructure, and absence of competitive polling or redistricting shifts. A Republican upset would require an unprecedented national swing, late scandal, or withdrawal by the incumbent, none of which appear imminent.
