New Jersey's 12th congressional district features an open seat following the retirement of longtime Democratic Representative Bonnie Watson Coleman. Democrat Adam Hamawy, a surgeon and Army veteran, secured the nomination in the June 2 primary, while Republican Gregg Mele advanced unopposed. The district's strong Democratic lean, demonstrated by Kamala Harris's double-digit margin in 2024 and consistent historical performance, underpins trader pricing on a sizable Democratic victory margin in the November 3 general election. With no major recent polling shifts or campaign events altering the fundamentals, the implied probabilities reflect the seat's structural advantage for Democrats and limited path for Republican gains.
