New York’s highest court has heard arguments in a redistricting lawsuit that could shape congressional lines in the state, setting the stage for races that could decide which party takes control of the House. The Court of Appeals hearing took place Wednesday in Buffalo. Democrats are seeking to scrap the state’s lines after losing congressional seats last year in a series of upsets that helped cede the House to Republicans. With Republicans controlling the House by a narrow majority, both parties have placed heavy emphasis on the coming congressional elections in New York and turned the state into an unlikely battleground.
