Sen. Mario Mattera

District 2 Republican First elected 2021

Mario Mattera, a Republican first elected in 2021 representing the R+3 SD-2 district on Long Island, has built his 2025 legislative identity around energy and transportation policy, sponsoring 60 bills with particular concentration in Energy (6 bills), Public Service (5 bills), and Vehicle and Traffic (4 bills), while serving as a member of the Transportation, Labor, and Energy and Telecommunications committees. His hearing record of 18 engagements reflects sustained focus on EV charging infrastructure, CLCPA cost transparency, battery storage safety, and Long Island Rail Road electrification, and he has cast 1,443 votes in the 2025 session at a 94.3% party loyalty rate, though he has broken with the Republican caucus on select environmental and labor measures including votes aligned with sustainable housing and worker rights bills. Electorally, Mattera has won his last three general elections by comfortable margins — 16.6 points in 2024 and 15.8 points in 2022 — with a base lean of R+11 in scenario modeling that rates the district Likely R even in a neutral environment, suggesting limited near-term vulnerability. His $205,128 raised in campaign finance from 2022–2026 draws heavily from construction and trades-adjacent donors — including $8,000 from Carnak Construction Inc. and $7,500 from Just Plumbing Corp. — a pattern that aligns with his bill sponsorship focus areas and his repeated floor advocacy for project labor agreements and prevailing wage protections.AI

S9005C An act to amend Chapter 268 of the Laws of 1996 (Public Protections and General Government Budget Bill) 2026-05-21 PASSED
