Delaware’s at-large congressional district maintains a strong Democratic tilt heading into the November 3, 2026 general election, supporting trader consensus that favors the Democratic nominee at 94.5 percent. Incumbent Sarah McBride, who won the seat in 2024 by nearly 16 points, faces Republican Joseph Arminio after both parties completed their September 15 primaries. Nonpartisan forecasters rate the contest Solid or Safe Democratic, reflecting the state’s consistent partisan performance and limited Republican infrastructure for statewide races. The Democratic primary required no vote, while Arminio prevailed among three GOP contenders. Late developments such as a major national shift in voter sentiment, an unforeseen scandal, or a significant health or campaign event could still alter the outcome before Election Day.
