When, why Democrats took the edge in Westchester, Mamaroneck

After a century of Republican political dominance, Democrats took the lead in voter enrollment in Westchester in the mid-1980s as a result of economic and demographic shifts that started in the 1970s and turned Westchester more urban. These included the influx of major corporations and their executives and young professionals - many likely from heavily Democratic New York City - settling in the county during a proliferation of office parks and corporate headquarters. In addition, Westchester's older cities upgraded their downtowns and housing and attracted more minority residents also more likely to be Democrats.

George Latimer, former Westchester County executive and now a congressman, looked back over the changes during his more than 35 years in public office and told Politico in 2022: "It's completely different. There has been a turnover. Long-time residents have packed up and moved to Florida,and they've been replaced by young professionals coming up out of the city or people moving in for corporate assignments in Westchester or the city - and they bring a different mindset."

By 1985, Democrats had taken the edge in voter registration, 166,000 to 161,000, according to The New York Times.

Still, the county - and Mamaroneck Town (including Larchmont and part of Mamaroneck Village) - voted for Republican presidential candidates through the 1980s - Ronald Reagan in 1980 and 1984 and George H.W. Bush in 1988. Then, the political changes kicked in. Democrats have carried the county and Mamaroneck Town in presidential elections since 1992.

In 2024, Westchester counted 307,381 registered Democrats to 118,169 registered Republicans. In Mamaroneck Town (including Larchmont and part of Mamaroneck Village), there were 10,967 registered Democrats and 3,501 registered Republicans, according to the Westchester County Board of Elections.
