Richard Tabor leads Polymarket trader consensus at 53.5% implied probability to win New Jersey's Republican U.S. Senate primary on June 2, driven by his string of county Republican organization endorsements, including Union, Atlantic, and Hunterdon—bolstered by a mid-April court ruling barring rival Alex Zdan from claiming the Union nod. Zdan holds at 27% with backing from Bergen, Passaic, and Mercer counties, plus recent campaign events, but faces headwinds from the endorsement dispute and muted fundraising across the field. Absent public polls, traders weigh establishment support and Tabor's state trooper-Army veteran profile against Zdan's media background amid low overall GOP donor interest; early voting begins soon, with turnout key in this low-profile race.
