California’s 26th congressional district carries a D+9 Partisan Voter Index and has consistently supported Democratic candidates in recent cycles. The June 2026 top-two primary confirmed state Assemblymember Jacqui Irwin as the Democratic nominee after she secured 41 percent, while Republican Samuel Gallucci advanced with 21 percent; the remaining Democratic vote split among multiple challengers. Incumbent Julia Brownley’s retirement opened the seat, yet the district’s underlying partisan composition and Irwin’s established name recognition in Ventura County have produced a wide consensus among forecasters rating the race Solid or Safe Democratic. Trader pricing at 94.5 percent for the Democratic outcome aligns with this structural advantage and the absence of late-breaking developments that would alter the balance before the November 3 general election. A national Republican surge, unforeseen candidate withdrawal, or turnout anomaly could still narrow the margin, though such shifts would require movement well beyond historical patterns in the district.
