Mayor Bill de Blasio, not far removed from his own failed presidential bid, said on Monday that there was “no way in the world” that his predecessor in City Hall, Michael R. Bloomberg, deserved the Democratic nomination for president.

“This is a Democratic Party today that’s getting more progressive, that wants to address the concerns of working people, that does not accept the status quo,” Mr. de Blasio said. “There’s no way in the world we should nominate a billionaire who epitomizes the status quo.”

Mr. de Blasio portrayed Mr. Bloomberg as being out of touch with current Democratic values, and suggested that Mr. Bloomberg’s 12-year tenure as mayor of New York was a showcase for some of his worst instincts.

“I think when he was mayor he had no understanding of the inequality crisis,” Mr. de Blasio said. “He was absolutely tone-deaf to what working people were going through in this city, and there were a number of other areas where he had a chance to do something and he just did not make it a priority.”
