The proposed maps drew immediate criticism in some quarters. Bill Mahoney, research coordinator for the New York Public Interest Research Group, described the proposed Senate map as containing "clearly the most gerrymandered lines in recent New York history." And Edward I. Koch, a former mayor of New York City who advocated for an independent redistricting process, said he was "disappointed in this result, and in the dishonorable lawmakers who openly pledged to do things differently this year." "What a shame - this is not reform in letter or in spirit," Mr. Koch said. Today, victory lies with the enemies of reform. In remarks to reporters on Thursday, before the maps were released, Mr. Cuomo seemed unsure about how to proceed, saying the redistricting issue was characterized by disagreement and uncertainty, and would inevitably wind up in front of a judge. But later Thursday afternoon, after the maps were released, Mr. Cuomo's spokesman, Josh Vlasto, issued a statement saying, "At first glance, these lines are simply unacceptable and would be vetoed by the governor."
