Trader consensus on Polymarket prices Richard Tabor as the slight frontrunner at 49.5% implied probability to win the New Jersey Republican Senate primary, with Alex Zdan close behind at 40.5%, capturing the closely contested dynamics in this low-turnout race. Recent internal polls and fundraising reports show Tabor's edge from stronger establishment endorsements and donor support, while Zdan builds momentum through grassroots organizing and appeals to Trump-aligned voters in a deep-blue state. Lower probabilities for Robert Lebovics, Justin Murphy, and others reflect their limited campaign infrastructure. Separation could emerge from upcoming debates, late endorsements, voter turnout efforts, or primary-day mobilization, as no single catalyst has yet broken the deadlock ahead of the June primary.
