The open seat, previously held by retiring incumbent Dwight Evans, sits in one of the nation’s most Democratic districts, where recent presidential results showed margins exceeding 75 points. No Republican candidate advanced from the primary, leaving independent Dennis Mahoney as the sole general-election opponent on the November 3, 2026 ballot. Election forecasters rate the contest Solid or Safe Democratic, aligning with trader consensus reflected in the 98 percent probability assigned to Rabb. Late developments such as a major scandal, candidate health event, or unusual turnout shift could still alter the outcome before election day.
