Republican Mike Lawler conceded to Democrat Cait Conley in New York’s 17th Congressional District before midnight, before the race had been officially called. Preliminary results showed Conley winning the closely contested seat by about five percentage points, an approximately 11-point shift toward Democrats compared with the 2024 congressional race.

The district, which includes Rockland and Putnam counties, most of northern Westchester County and parts of southern Dutchess County, became a focus of debate over energy prices, data centers and nuclear power. Climate policy was less often named directly, but Conley said she would treat climate change as a national security priority.

Westchester County reported widespread problems with ballot-scanning machines on Election Day, delaying results. Despite concerns the problems might deter some voters, Conley won the county by 34 points, according to preliminary results.

Lawler made energy costs a central campaign issue, blaming New York Democrats for higher utility bills. His record also included millions of dollars in contributions from utility-related political Action committees and previous work as a registered lobbyist for a natural-gas advocacy group backed by utilities and fossil-fuel interests. He supported reopening the shuttered Indian Point nuclear plant and expanding domestic oil and gas production.

He also highlighted more than $328,000 in payments from two AI surveillance companies disclosed in Conley’s financial filings, as he sought to portray her as aligned with the artificial intelligence industry. The result suggests she was able to counter that criticism.

Conley has said she would increase federal investment in clean energy, protect open spaces, hold corporate polluters accountable and press the administration to rejoin the Paris climate agreement. She opposes reopening Indian Point and has pledged to address PFAS, commonly known as “forever chemicals.”

Environmental advocates in the district welcomed her win as an opportunity to advance climate priorities. Local concerns include proposals for new nuclear and natural gas plants, pollution from an aging waste incinerator, plastic use and the restoration of funding for solar programs. Advocates also urged Conley to follow through on her campaign positions.

A separate concern is the ongoing federal court appeal brought by New York Attorney General Letitia James, which seeks to reverse a federal decision allowing the proposed discharge of radioactive wastewater from Indian Point. Environmental attorney Susan Shapiro said preventing a large-scale release into the Hudson River should be a priority, while also expressing concern about Conley’s and Governor Kathy Hochul’s positions on nuclear power.

The election also changed local leadership in Clarkstown, where Democrat Sylke Jackson won a Town Council seat as the town shifted from an entirely Republican council to an entirely Democratic one. Jackson said the new council could act on local environmental issues.
