Ossining's incumbent Mayor William R. Hanauer had built up an insurmountable lead with more than half of the village's votes counted in tallies Tuesday night.
By 11 p.m., Hanauer had 2,268 votes -- almost three times as many as his challenger, Republican Linda Cabral Marrero, according to unofficial results from the Westchester County Board of Elections.
The win would give Hanauer, a Democrat, a fourth term as mayor. Previously, Hanauer served as a trustee and a leader of a neighborhood association. He made headlines earlier this year when he married his longtime partner, Princeton University professor Alan Stahl.
Marrero, a lifelong Ossining resident, ran on promises to preserve historic aspects of the village and combat what she called urban sprawl. She also appealed to voters by promising to develop the village's waterfront.
Hanauer will earn more than $12,000 annually as mayor during his fourth term.
