- Cory Booker (D) seeks his third full Senate term in the Class 2 seat he has held since 2014 — won the Democratic primary unopposed after challengers failed to qualify on June 2, 2026.
- Harris won New Jersey by +6.1 pts in 2024 (down from Biden +16.1 in 2020) — the state is shifting, but Democrats retain a structural advantage that makes Booker a solid favorite.
- Republican primary June 2, 2026: Alex Zdan, Richard Tabor, Justin Murphy, and Robert Lebovics are competing for the nomination. No frontrunner has emerged; no high-profile candidate has entered the race.
- Note: Andy Kim (D) holds New Jersey's Class 1 seat (elected November 2024, up in 2030) — he is not involved in this 2026 race.
New Jersey is rated Likely Democratic. Booker enters the race as a two-term incumbent with strong fundraising and broad name recognition. The structural Democratic lean of the state, combined with the absence of a top-tier Republican challenger, makes this race a Democratic hold barring an unusual national environment.

Cory Booker — Incumbent Profile
Cory Booker has represented New Jersey in the US Senate since October 2013, when he won a special election to fill the seat vacated by the death of Frank Lautenberg. He won his first full term in 2014 and was re-elected in 2020 by 16.3 points over Republican Rik Mehta. A Yale Law graduate and Rhodes Scholar, Booker served as Mayor of Newark (2006–2013) before his Senate career, building a national profile through his aggressive policy advocacy and social media presence.
Booker ran briefly for the Democratic presidential nomination in 2020 before withdrawing in January of that year. He is among the most prominent Black politicians in the United States and has been a leading voice on criminal justice reform, including co-authoring the First Step Act (2018) with bipartisan support. His national visibility and fundraising network give him a structural advantage in any statewide race. He is a vocal progressive on social issues but has worked across the aisle on several high-profile bills, including the EQUAL Act and bipartisan legislation on infrastructure and hunger relief.
The 2026 race is structurally favorable for Booker: a +6.1 presidential baseline, no high-profile Republican challenger yet, and the historical pattern of New Jersey returning Democratic senators for the past 25 years. His main vulnerability would be a national anti-Democratic wave severe enough to overcome both his incumbency advantage and the state's partisan lean.
New Jersey has two Democratic senators in 2026. Cory Booker holds the Class 2 seat (up in 2026) and Andy Kim holds the Class 1 seat (elected 2024, up in 2030). Kim won the Class 1 seat in November 2024 with 62.1%, replacing interim senator George Helmy, who had been appointed by Gov. Murphy after Bob Menendez resigned following his federal corruption conviction. Menendez's resignation and Kim's election are entirely separate from Booker's Class 2 seat.
Republican Path to Flipping New Jersey
New Jersey has not sent a Republican to the US Senate since Bob Franks was defeated by Jon Corzine in 2000. The state's structural Democratic lean — driven by urban Essex, Hudson, and Camden counties plus diverse suburban Middlesex and Bergen counties — makes Senate races very difficult for Republicans in normal political environments.
Republican strategists nonetheless see a theoretically possible path in 2026 for several reasons: Harris won New Jersey by only +6.1 points in 2024 (compared to Biden's +16.1 in 2020), a 10-point swing toward Republicans in four years. Chris Christie won the governorship twice (2009, 2013) and Jack Ciattarelli nearly defeated Phil Murphy in 2021, suggesting suburban crossover appeal is achievable for the right candidate. New Jersey's famously high property taxes and cost-of-living pressures generate a standing anti-establishment resentment that Republican candidates can tap.
The decisive variable is candidate quality. No A-tier Republican has entered the race as of May 2026 — the four declared candidates (Zdan, Tabor, Murphy, Lebovics) are not nationally known figures. Without a credible, well-funded challenger with crossover appeal in Bergen and Morris counties, the state's baseline makes a Republican win unlikely even in a good national GOP environment.

2026 Senate Race Context & National Outlook
The 2026 midterm elections are taking place in an environment shaped by significant economic uncertainty. Trump's Liberation Day tariffs triggered a consumer confidence collapse and PCE inflation surged to 4.5% in Q1 2026. The Trump approval rating stands at 38.1% approve / 59.2% disapprove — among the lowest for any first-year president since modern polling began. The Generic Ballot shows Democrats with a consistent +6.0 advantage, a historically predictive indicator of significant House seat gains.
In the Senate, 33 Class 2 seats are up in 2026. Republicans must defend seats in Georgia, Iowa, North Carolina, Alaska, and Texas, while Democrats defend Nevada, New Hampshire, Michigan, Minnesota, and Virginia. Key battleground races that will determine Senate control include Georgia (Jon Ossoff, D), Iowa (open seat, Ernst retires), Nevada (Jacky Rosen, D), and Alaska (Lisa Murkowski, R). The full Senate map is at the Senate 2026 overview.
Issue-level polling context: The top issues driving 2026 are the economy and tariffs, healthcare, immigration, and Social Security. See the Battleground Tracker for the latest state-level polling and the Trump Policy Tracker for executive action context.
