The endorsement from Mayor Zohran Mamdani and backing from the New York City chapter of the Democratic Socialists of America have positioned Assembly Member Claire Valdez as the clear leader in the June 23 Democratic primary for New York’s 7th Congressional District. Trader consensus reflects this momentum in a contest against Brooklyn Borough President Antonio Reynoso, who carries the endorsement of retiring Representative Nydia Velázquez along with support from labor unions and local elected officials. Recent campaign activity has centered on Puerto Rico policy priorities and candidates’ district ties in the North Brooklyn and Western Queens area, while lower-polling entrants such as City Council Member Julie Won and others trail significantly. The primary timeline and these endorsement dynamics continue to shape assessments of the race ahead of the June vote.
