Legislators Submit Redistricting Plans to a Judge ALBANY - Legislative leaders, unable to agree on how to reduce New York's Congressional delegation by two seats, submitted competing plans late Wednesday night for a federal judge to consider as she develops a redistricting plan that could be imposed by the court. New York must reduce the size of its congressional delegation to 27 from 29 seats because of population shifts identified in the 2010 census, and the issue has taken on increasing urgency because a federal judge in an unrelated case has ordered the state to hold its congressional primary, normally scheduled in September, on June 26. The Senate's Republican majority and the Assembly's Democratic majority, as expected, have proposed eliminating the mid-Hudson Valley district currently overseen by Representative Maurice D. Hinchey, a Democrat not seeking re-election, and distributing its territory among several surrounding upstate districts. But the lawmakers differed on how to remove a second seat from the state's map. Both parties propose eliminating a district in the New York City area, but they could not agree on the details. The Senate Republicans proposed to carve up the Queens and Nassau County district represented by Gary L. Ackerman, a Democrat. As a result, to remain in Congress, Mr. Ackerman would face the prospect of running against a fellow Democrat, Representative Carolyn McCarthy, in a district almost entirely in Nassau County. The Assembly Democrats proposed to eliminate the district in Brooklyn and Queens represented by Bob Turner, a Republican who scored an upset victory in the special election last fall to replace Democrat Anthony D. Weiner. The Assembly Democrats proposed to fold that district into a neighboring one, currently represented by Joseph Crowley, who is also the Queens Democratic Party chairman. The new district would be based entirely in Queens, and therefore advantageous to Mr. Crowley. The Assembly Democrats also proposed carving up the district represented by Mr. Ackerman. Mr. Ackerman's current residence would fall in the district represented by a fellow Democrat, Representative Steve Israel. Democrats would also create a new, heavily Democratic, district in Queens and the Bronx that would include roughly half of the territory currently represented by Mr. Ackerman. The federal magistrate will have several other proposals to consider as she develops her own map of the state's congressional district. The Republican minority in the Assembly made a proposal, as did several government reform and civil rights groups, and the court is inviting proposals from the public through Friday. The federal magistrate judge handling the Congressional redistricting process, Roanne L. Mann, plans to hold a hearing on Monday to gather feedback on the competing plans. Judge Mann has until March 12 to submit her own redistricting plan to a panel of federal judges that could then impose it on the state.
