Richard Tabor leads trader consensus at 53.5% implied probability to win New Jersey's Republican U.S. Senate primary on June 2, propelled by endorsements from at least seven county Republican organizations—including Atlantic, Hunterdon, Ocean, Somerset, Union, Middlesex, and Hudson—that secure him prime ballot positions via the influential county line system, critical in low-turnout primaries. Alex Zdan follows at 31.5% with backing from Monmouth, Passaic, Cumberland, Salem, and parts of Mercer, bolstered by his media background and recent events like the May 28 NJ Globe debate announcement. Absent public polling, markets weigh party machinery heavily amid GOP donors' reluctance; late momentum or turnout surprises could shift the closely contested race.
