Delaware’s at-large congressional district maintains a strong Democratic tilt ahead of the November 3 general election, with all major forecasters rating the contest Solid or Safe Democratic. Incumbent Sarah McBride advanced unopposed in the September 15 Democratic primary, while Joseph Arminio emerged as the Republican nominee after defeating two challengers. The state’s consistent partisan performance in recent cycles, combined with McBride’s prior double-digit victory margin, underpins trader consensus near 99 percent for the Democratic nominee. A late-breaking scandal, severe health event, or unusually large national partisan swing would be required to alter the outcome in the remaining weeks before Election Day.
