Then, campaigning in October 2025, he made the day about himself — the suspicion he grew up under, the airport questioning, the indignity of it. Set that beside a childhood spent in rooms with Bill Clinton, Bill Gates, and Jeff Bezos, and the martyrdom is a little hard to locate.

Which brings us to this week. The 9/11 families asked him to stay away from the ceremony at the World Trade Center. More than 100,000 people signed a petition backing them. These are not political operatives. They are people who want one morning a year to say their husband’s name at the place he died, without a politician nearby who treats their grief as a preamble.

Mamdani says he’s coming anyway.

Here’s the thing his defenders will never understand about that date: the job of any mayor on September 11 is to be small. Show up, stand in back, read the names, say nothing clever. Rudy Giuliani earned the right to be a main character on that ground and still had the sense not to claim it forever. Mamdani hasn’t earned an inch of it and is claiming all of it.

He’ll get his photograph. He’ll get his statement about a better world. And a lot of Americans watching — including plenty who don’t follow New York politics and couldn’t name his opponent — will file away exactly what kind of person overrules grieving families to make sure he’s in the frame.

That bill comes due in November. Not his November. Everyone else’s.
