The non-competitive 2026 New Jersey Senate contest between incumbent Democrat Cory Booker and Republican Justin Murphy has produced moderate trader expectations for total votes cast, with the 3M-3.2M range leading at 43.5%. The race's solid Democratic rating, wide projected margin near 19 points, and lack of general-election polling have limited campaign intensity and voter mobilization since the June primaries. Light Republican primary participation and standard midterm turnout patterns below the 2024 presidential level anchor probabilities in the 2.8M-3.6M bands. Democratic registration advantages and expanded early and mail voting options could support participation in urban and suburban areas, while the absence of competitive statewide races reduces broader get-out-the-vote efforts.
