Mayor Eric Adams said Tuesday he wants the city’s Landmarks Preservation Commission to designate two Christopher Columbus statues.  He deserves thanks for agreeing to take a long-overdue step to preserve the explorer’s central place in American history and Italian American identity. It’s a stark contrast from mayoral front-runner Zohran Mamdani, who in 2020 tweeted an image of himself giving a latex-gloved middle finger to Columbus’ statue in Astoria captioned, “Take it down.” No, Assemblyman.
