What the New Jersey US Senate election decides
The Senate confirms federal judges and cabinet officers, ratifies treaties, and can stop legislation the House passes. With a six-year term and a hundred-member chamber, a single seat is a larger share of the institution than any House district, which is why Senate races draw national money into state contests.
Each state sends two senators regardless of population, so this seat carries the same weight as California's or Wyoming's. New Jersey voters fill it alongside all 12 of the state's House seats, and a Senate term runs six years, spanning two future Congresses and, in this case, the next presidential election.
How New Jersey votes
New Jersey is a dense suburban state between two great metros, with property taxes, transit and utility costs as constants of its politics. Democrats lead statewide, though margins have varied sharply cycle to cycle. That backdrop is the ground any New Jersey campaign fights on, and it is what the Electorate HQ simulation reads first when it weighs a ticket's platform against this contest.
About this race
The 2026 United States Senate election in New Jersey was held on November 3, 2026 to elect a member of the United States Senate to represent the state of New Jersey. Democratic incumbent Cory Booker was re-elected to a third full term, defeating Republican former Tabernacle deputy mayor Justin Murphy.
Primary elections were held on June 2. Booker ran unopposed for the Democratic nomination. In the Republican primary, Murphy won the nomination with 33.3% of the vote over state trooper Richard Tabor and journalist Alex Zdan.
Booker defeated Murphy by a margin of 27.2%, marking the strongest performance of his senatorial career and the best performance for a New Jersey Democrat in a US Senate race since 1984. He also flipped two reliably Republican counties, Hunterdon and Monmouth, making him the first Democrat to win these counties in a statewide race since the 2001 New Jersey gubernatorial election and the 1984 Senate race, respectively.

Analysis covering New Jersey
The 2026 Senate map covers 62% of the country and 70% of the states
Thirty-five of fifty states vote for Senate this year. Weighted by people rather than states the share drops, and that gap is the design of the chamber.
Twenty-six states elect a senator and a governor on the same day in 2026
The overlap between the Senate class and the gubernatorial cohort is a coincidence of two unrelated calendars, and it decides where money goes.
