NJ-07 Voter Registration: Democrats Added 5,485 Voters This Year to Republicans' 1,397 — and Still Trail by 16,197 in Kean's District
The official October 1 registration book for the 7th District tells two stories at once: Democrats are registering faster in 2026, and Republicans still hold the bigger army in the district Tom Kean Jr. is defending against Rebecca Bennett.
Two days before Election Day, the most basic document in New Jersey's closest House race is the registration book. According to New Jersey Division of Elections figures dated October 1 and compiled in the reporting read by this desk, the 7th Congressional District held 639,566 registered voters: 218,268 Republicans, 34.13 percent of the roll, against 202,071 Democrats, 31.60 percent — a Republican advantage of 16,197 voters in the district Republican Rep. Tom Kean Jr. defends against Democrat Rebecca Bennett on Tuesday.
The year's movement runs the other way. Since January 1, Democratic registration in the district has grown by 5,485 voters, against a net Republican increase of 1,397 — Democrats adding voters at nearly four times the Republican pace through 2026. That is the same energy the early-vote numbers showed this week, when Democrats in the district passed their entire 2025 advance-ballot total before the final day of early voting began. Registration and turnout are different things, but in NJ-07 this year they point the same direction.
The cautions are structural. Unaffiliated voters — the largest bloc in much of New Jersey — sit outside both party columns, and a registration edge has never voted by itself; Kean's 16,197-voter advantage is the cushion his campaign starts with, and Bennett's registration and early-vote pace is the trend hers is counting on. The district — Hunterdon and Warren counties plus parts of Morris, Somerset, Sussex and Union — also gives voters a third name on the official ballot, Seamus Patrick O'Toole. On Tuesday, the only registration figure that will matter is how many of the 639,566 actually show up.
