Blas put us all in this jam

Bill de Blasio’s New York just gets worse.

The Post’s two front-page stories about traffic jams reflect City Hall’s incompetence and arrogance. And what does de Blasio care? He’s got a helicopter, so sitting in traffic is for little people.

Daily gridlock is one of many problems that underscore Gotham’s decline. Filthy conditions in public-school cafeterias make the stomach turn, yet educrats brush it off with a breezy statement about being dedicated to “providing students with nutritious meals in cafeterias that are clean and safe.”

But the cafeterias are neither!

The homeless situation is so bad that de Blasio will pay families to take in relatives. If that sounds like an open-ended invitation to graft, it is. And expect the homeless numbers to soar higher regardless.

Then there’s de Blasio’s refusal to turn over e-mails with private political consultants he calls “agents of the city.” After The Post and others sued, de Blasio released some but redacted so much material that it’s obvious he’s hiding something.

The feds have all the emails as part of their probes into a possible de Blasio pay-to-play scheme, so the mayor might as well release them all and take his lumps. Instead, he dribbles them out, including a big batch on the night before Thanksgiving.

The episode was even too much for one usual ally, Public Advocate Letitia James. She ripped his use of the consultants as a “violation of ethics.”

Ethics and de Blasio? That’s an oxymoron.
