I write about New York City: its politics, its policy and how it's governed.
I'm managing editor of Vital City, a journal of ideas about New York policy. For sixteen years I edited opinion at the New York Daily News, as op-ed editor and then editorial page editor.
Before that, speechwriting and policy in New York and Washington. Years ago I wrote headlines for The Onion. I publish Thoughts About Stuff on Substack. I live in Brooklyn with my wife and our two daughters.
Twenty years of columns and editorials, mostly about New York.
