Asm. Joe DeStefano
Joe DeStefano represents AD-3, a nominally Democratic-leaning district (D+1 by registration, with Democrats at 31.8%, Republicans at 30.6%, and Independents at 31.9%) in what is a high-homeownership (80.3%), majority-white (67.1%) suburban Suffolk County community with a median household income of $109,846. Despite the district's marginal partisan lean, DeStefano has won comfortably since first being elected in 2018 by 8.0 points, expanding his margins to 13.8 points in 2020, 27.6 points in 2022, and 20.6 points in 2024; his 2026 outlook is rated Likely R in neutral and Democratic-favorable environments and Safe R in a Republican-favorable environment, with a base lean of R+14. His 57 sponsored bills in the 2025 session concentrate on Penal law (5 bills), Criminal Procedure (4 bills), and Suffolk County-specific legislation (4 bills), with additional sponsorship across Executive, General Municipal, Highway, Legislative, and Retirement law areas, reflecting a local and public-safety-oriented legislative focus. No committee chairmanship or lobbying sector data is identified in this brief.AI
Vulnerability Index AD-3
Base lean: R+14
Scenario model: ±5pt national environment shift applied to district base lean (R+14). Base lean blends voter registration (40%) with recent contested general election margins (60%), using up to the last 4 general elections with margins under 40 points. Ratings: Safe D/R = 15+ pts, Likely = 8–14 pts, Lean = 3–7 pts, Toss-up = within 2 pts. Generic ballot from Silver Bulletin (Nate Silver), as of 5/1/2026. Not a prediction — reflects structural competitiveness under different cycle environments.
