Read my lips: I don’t care. It’s an irrelevancy,” Mayor de Blasio declared yesterday.

Well, that’s a little cold.

De Blasio is back in the deep weeds, his minions having booted vagrants from a couple of Brooklyn subway stations so the bums wouldn’t spoil a weekend campaign photo-op.

And getting caught at it.

And then lying about it.

And then getting caught in the lie, which clearly has made the mayor a tad peevish. This is understandable, because the episode exposes him as a man who can’t even stage a four-subway-stop publicity stunt — even as he runs for a second term as chief executive of the world’s greatest city.

(God surely must love New York, given the people it manages to survive.)
