New York’s 7th Congressional District, covering parts of Brooklyn and Queens, carries a Cook Partisan Voting Index of D+25 and has delivered Democratic margins above 70 percent in recent cycles. Longtime Representative Nydia Velázquez’s retirement opened the seat, but Democratic Assemblywoman Claire Valdez secured the nomination in the June 23, 2026 primary with 56 percent of the vote against Brooklyn Borough President Antonio Reynoso and other challengers. Nonpartisan ratings classify the general election as Solid or Safe Democratic, with Republican nominee Melvin Rivera facing structural headwinds in a district where registered Democrats vastly outnumber Republicans. Trader consensus at 95.5 percent Democratic reflects these entrenched partisan demographics and the absence of competitive polling or fundraising data suggesting an upset. A realistic shift would require an unforeseen national political realignment or a major development involving the Democratic nominee between now and November 3.
