Incumbent Laura Gillen maintains a commanding lead in the June 23, 2026 Democratic primary for New York’s 4th congressional district, reflecting her substantial fundraising advantage and party establishment backing after crossing party lines in January 2026 on Department of Homeland Security funding that included Immigration and Customs Enforcement appropriations. That vote prompted challenges from former state Assembly member Taylor Darling and lesser-known candidates Nicholas Sciretta and Gian Jones, who positioned themselves as more progressive alternatives on immigration issues. Gillen’s edge stems from over $2 million in receipts and $1.5 million cash on hand compared with each rival’s under $30,000, plus an endorsement from Nassau County Democratic leader Jay Jacobs. With no public polls available and a closed primary favoring low-turnout incumbents, the divided challenger field has reinforced trader consensus around her structural advantages ahead of primary day.
