In New Jersey's 12th Congressional District Democratic primary for the open seat vacated by retiring Rep. Bonnie Watson Coleman, trader consensus slightly favors East Brunswick Mayor Brad Cohen at 33% following his March 16 endorsement by the influential Middlesex County Democratic Organization—the district's most populous county—building on his early fundraising lead. State Assemblywoman Verlina Reynolds-Jackson remains close at 28% with established legislative name recognition, while Susan Altman garners 19% via progressive backing like Princeton's grassroots groups. The fragmented field of over a dozen candidates, lack of public polling, and ideological tensions—such as Cohen's Israel support drawing retiring incumbent criticism—keep the contest tight; additional county endorsements, candidate forums, or Q1 fundraising disclosures before the June 2 primary could consolidate support and widen gaps.
