NEW YORK (AP) — Republicans picked up at least five House seats across New York and could boost the number to six as the antiestablishment, anti-incumbent wave sweeping midterm elections reached into one of the nation’s most reliably blue states.

Democrats lost House seats from New York City to Rochester despite strong wins for the party at the top of the ticket. Andrew Cuomo’s win over Republican Carl Paladino in the governor’s race and twin victories for Sens. Chuck Schumer and Kirsten Gillibrand over underfunded and largely unknown GOP opponents weren’t enough to stem deep losses down the ballot.

At least one race remained too close to call. First-term Democratic Rep. Dan Maffei and Republican Ann Marie Buerkle were in a dead heat in the Syracuse-area 25th district.

In Staten Island, Republican Michael Grimm scored an upset win over first-term Democratic Rep. Michael McMahon. Grimm, a retired FBI agent, narrowly defeated McMahon in the most conservative of New York’s five boroughs despite McMahon’s effort to portray himself as independent from his party’s leadership in Washington.
