A Democratic surge in the 2026 midterms, fueled by national sentiment against the incumbent president's party, produced an upset victory for Cape May Mayor Zack Mullock over four-term Republican Representative Jeff Van Drew in New Jersey's 2nd Congressional District. Mullock secured a narrow but decisive lead of roughly 51% to 48% in unofficial tallies, prompting Van Drew's concession on election night before major outlets called the race. Late Democratic super PAC spending exceeding $1.5 million amplified Mullock's emphasis on affordability and local infrastructure, while Van Drew's alignment with the president became a clear liability in a district that had favored Republicans by double digits in prior cycles. Trader consensus assigns Mullock overwhelming probability of the win based on these confirmed results and procedural momentum. Only unresolved mail ballots or certification disputes could theoretically alter the outcome, though such shifts remain highly improbable given the margin and concession.
