Forget Mamdani. New York's real political shift happened everywhere else.
ALBANY, New York — Zohran Mamdani’s decisive win in New York City — along with key victories in New Jersey and Virginia — suggested Democrats are headed into the midterms from a position of strength. But they didn’t capture how deep that strength ran.
Across suburbs, rural counties and small towns in New York, Democrats posted electoral gains that rival — and in many cases surpass — the party’s 2017 “Blue Wave.” In a state with enough competitive House races to decide control of the chamber, the outcome amounts to a wakeup call for already-wary Republicans.
New York Democrats once viewed the 2017 elections as among their best ever. The Blue Wave that year was driven by purple suburbs making a hard shift left. This year in New York, that tilt was felt even more widely — with Democrats in every corner of the state pointing to economic uncertainty exacerbated by President Donald Trump’s policies as voters’ top concern.
“It was about peoples’ anxiety,” said Leslie Berliant, who ousted a Republican incumbent to win a seat in the Otsego County Legislature. “It definitely was a feeling that we don’t feel protected by what’s happening in the federal government, and we need to make sure we have people in place at the local level who care about our needs. Democrats ran on that, and I think it worked.”
