Marenco's term ended January 13, 2026 after he chose not to seek re-election to focus on his role as Executive Director of the North Bergen Housing Authority. His single term was marked by the passage of A3871, requiring Latino and Hispanic history in all NJ K-12 schools, a first-of-its-kind law in the state.
Marenco was initially on Jersey City Mayor Steven Fulop's gubernatorial slate before withdrawing from his re-election bid. State Senator Brian Stack backed Gabe Rodriguez and Larry Wainstein to replace him in LD-33. Won his 2023 general election with 48.5% of the vote, defeating Republican Lea Sherman.
