Floor Speeches: In Opposition (26) AI

A11550 Amending the Judiciary Law in relation to judicial departments 2026-06-04

Criticized the timing and process, noting the bill was dropped at the end of session both years despite having a full year between sessions to conduct proper procedures, and questioned why public hearings and Judiciary Committee review were not pursued.

A11557 An act to amend the Election Law, in relation to the form of submission and abstract for proposed amendments to the Constitution 2026-06-04

The current process works and is longstanding. Transferring authority from the statutorily bipartisan Board of Elections to a supermajoritarian Legislature injects partisanship into a process that should remain neutral. The Legislature is inherently biased in favor of amendments it votes to place on the ballot.

A04674 An act to amend the Labor Law in relation to employment advertisements and ghost jobs 2026-06-02 PASSED

Argued the bill penalizes business growth by fining companies $2,500 per platform for leaving ads up slightly too long, potentially costing $25,000+ for a business hiring its 101st employee. Called it anti-business legislation.

A04674 An act to amend the Labor Law in relation to employment advertisements and ghost jobs 2026-06-02 PASSED

A10102 An act to amend the Real Property Law, in relation to enacting the 'Low Impact Landscaping Rights Act' 2026-03-30 PASSED

While skeptical of HOAs generally, expressed concern about existing contracts and potential constitutional issues under the Contracts Clause, voting against the bill on constitutional grounds.

Scenario model: ±5pt national environment shift applied to district base lean (R+35). 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 (Assembly districts are smaller and more homogeneous than Senate districts, so tighter thresholds are used). Generic ballot from Silver Bulletin (Nate Silver), as of 10/20/2026. Not a prediction — reflects structural competitiveness under different cycle environments.
