The grueling midterm battles that arose from New York’s redistricting chaos continued on Wednesday, with tight races in a couple of consequential districts still up in the air — elections that could help decide the balance of power in Congress.

Republicans have flipped four seats, including that of Sean Patrick Maloney, the chairman of the Democratic Congressional Campaign Committee, whose concession constituted a humiliating loss for Democrats.

With supermajorities in Albany, Democrats in New York had hoped to use redistricting to cement their grip on the state and perhaps even offset some of the influence of Republicans in other states. But the maps they drew were rejected by a court as gerrymandered, leaving the job to a special master, who drew a handful of competitive districts, some of which yielded tight races that have yet to be called.

Here’s where things stand in New York:

On Long Island, Republicans won all four congressional seats — flipping two.

In New York’s Third Congressional District, the Democratic activist and businessman Robert Zimmerman lost to George Santos, who attended the Jan. 6. rally in Washington, D.C. The contest appeared to be the first in New York history to pit two openly gay men against one another for a seat in Congress. The district was previously held by Representative Tom Suozzi, a Democrat who launched an unsuccessful run for governor earlier this year.

In the Fourth Congressional District on the South Shore, the retired police detective Anthony D’Esposito, a Republican, defeated the Democrat and law professor Laura Gillen, to claim the district formerly held by Representative Kathleen Rice, a Democrat.

The Republican Andrew Garbarino held onto his seat in the Second Congressional District. And on the eastern tip of Long Island, the Republican Nicholas LaLota defeated his Democratic opponent, Bridget Fleming, in the race to fill Representative Lee Zeldin’s seat.
