A state court formally approved New York’s new congressional map late Friday, ratifying a slate of House districts drawn by a neutral expert that could pave the way for Democratic losses this fall and force some of the party’s most prominent incumbents to face off in primary matches.
, approved just before a midnight deadline set by Justice Patrick F. McAllister of State Supreme Court in Steuben County, effectively unwinds an attempted Democratic gerrymander, creates a raft of new swing seats across the state, and scrambles some carefully laid lines that have long determined centers of power in New York City.
Jonathan R. Cervas, the court-appointed mapmaker, made relatively minor changes toreleased earlier this week whose sweeping changes briefly united both Republicans and Democrats in exasperation and turned Democrats against each other.
In Manhattan, the final map would still merge the seats of Representatives Carolyn Maloney and Jerrold Nadler, setting the two Democratic committee leaders, who have served alongside each other for 30 years, onto an increasingly inevitable collision course.
Another awkward Democratic primary loomed up the Hudson in Westchester County, where two Black Democratic House members were drawn into a single district.
But the worst outcome for Democrats appeared to be averted early Saturday morning when one of the incumbents, Representative Mondaire Jones, said he would forego re-election in his Westchester seat. He said he wouldin Lower Manhattan and Brooklyn, a race that has already drawn , the former New York City mayor, but which no other sitting House member is expected to enter.
Republicans were already eying pickup opportunities in the suburbs of Long Island and in the 18th and 19th Districts in the Hudson Valley that could help them retake control of the House.
And in New York City’s only Republican-held district, Representative Nicole Malliotakis breathed a sigh of relief that Mr. Cervas had reversed one of the boldest moves by the Democratic leaders in the State Legislature, when they inserted liberal Park Slope, Brooklyn, into her Staten Island-based district.
Some of the most notable changes between the initial and final district lines came in historically Black communities in Brooklyn, where Mr. Cervas reunited Bedford-Stuyvesant and Crown Heights into single districts. He had facedand civil rights groups after his first proposal divided them into separate seats.
What to Know About Redistricting
Responding to feedback from community groups, Mr. Cervas also revised the map to reunite Manhattan’s Chinatown with Sunset Park in Brooklyn, another heavily Asian American community, in the 10th Congressional District. In each case, he said the communities had been “inadvertently split” in his first proposal.
Justice McAllister’s order approving the congressional and additional State Senate maps on Friday makes New York one of the final states in the nation to complete its decennial redistricting process.
But both parties were already girding late Friday for the potential for civil rights or political groups to file new, long-shot lawsuits challenging the maps in state or federal court.
Justice McAllister used the unusualto rebut criticisms leveled at Mr. Cervas and the court in recent days, as the maps were hastily drafted out of public view. He conceded that the rushed time frame was “less than ideal” but defended the final maps as “almost perfectly neutral” with 15 safe Democratic seats, three safe Republican seats and eight swing seats.
“Unfortunately some people have encouraged the public to believe that now the court gets to create its own gerrymandered maps that favor Republicans,” wrote Justice McAllister, a Republican. “Such could not be further from the truth. The court is not politically biased.”
The final map was a stark disappointment for Democrats, who control every lever of power in New York and had entered this year’s decennial redistricting cycle with every expectation of gaining seats that could help hold their House majority. They appeared to be successful in February, whena congressional map that would have made their candidates favorites in 22 of 26 districts, an improvement from the 19 Democrats currently hold.
But Republicans sued in state court, and Justice McAllister, a judge in the state’s rural Southern Tier, ruled that the maps violated a 2014 state constitutional amendment outlawing partisan gerrymandering and reforming the mapmaking process in New York. In late April, the New York Court of Appeals, the state’s highest court,and ordered a court-appointed special master to redraw the lines.
Justice McAllister appointed Mr. Cervas, a postdoctoral fellow at Carnegie Mellon with few ties to New York and scant experience drawing state lines, and delayed the congressional and State Senate elections until Aug. 23.
On Friday, Mr. Cervas produced aexplaining the rationale of his map, in which he tried to balance the need to protect communities of shared interest, existing districts, and other constitutional requirements.
Mr. Cervas eliminated one district overall, carving it out of central New York to shrink the state’s congressional delegation to 26. The change was required afterwith national population growth in the 2020 census.
How U.S. Redistricting Works
What is redistricting? It’s the of congressional and state legislative districts. It happens every 10 years, after the census, to reflect changes in population.
He made a slew of other changes across the state, responding to a crush of feedback to the initial proposal. For instance, Mr. Cervas reoriented his maps for Long Island considerably, creating districts that divided the island north-south rather than east and west, but kept them highly competitive.
Still, in his final congressional map, Mr. Cervas rejected pleas by Democrats and various interest groups to revert to a traditional east-west split of Manhattan. Doing so would have allowed Mr. Nadler and Ms. Maloney to run in their own districts, avoiding a messy primary conflict, but the special master wrote that he “did not find a compelling community of interest argument for changing the configuration.”
Mr. Nadler and Ms. Maloney have both declared their intentions to run in the newly created 12th Congressional District, which comprises central Manhattan.
“The new district belongs to no individual candidate, but instead to the voters who call it home,” Mr. Nadler said early Saturday morning.
Just to the south, a growing number of candidates have declared their interest in running for a newly reconfigured 10th District, which encompasses all of Lower Manhattan and a large swath of Brooklyn, including Park Slope and Borough Park.
Mr. de Blasioon Friday before the lines were finalized. Hours later, Mr. Jones surprised Democrats by announcing that he would follow suit, despite having minimal ties to the district.
“This is the birthplace of the L.G.B.T.Q.+ rights movement,” said Mr. Jones, who is gay. “Since long before the Stonewall Uprising, queer people of color have sought refuge within its borders.”
Representative Nydia Velazquez lives within the new district lines, but she has previously said she intends to run this year in the nearby Seventh District.
Mr. Jones’s decision will help avert another tense intraparty showdown in the Lower Hudson Valley.
The potential conflict emerged earlier this week, when Representative Sean Patrick Maloney, the D.C.C.C. chairman tasked with protecting the House majority, announced that he would seek to represent territory currently included in Mr. Jones’s seat. The decision would have forced Mr. Jones to compete in a primary with either Mr. Maloney or a fellow progressive congressman, Jamaal Bowman, in the neighboring 16th District.
With the maps finalized, other candidates across the state were expected over the weekend to announce campaigns and begin collecting petitions to get on the ballots.
Two upstate Republican incumbents also appeared to have avoided a potential primary conflict by Saturday morning. Representative Claudia Tenney said she would run for the new 24th District stretching from the outskirts of Buffalo to the eastern shore of Lake Ontario, and Representative Chris Jacobs said he would run for the 23rd District covering the Southern Tier.
