City First Lady Chirlane McCray revealed Wednesday that her son, Dante, and daughter, Chiara, may have broken ranks with Mom and Dad to support Bernie Sanders.

When asked whether she and Bill have discussed the election with their kids, McCray told ­jezebel.com: “Oh, yes. The discussions are . . . ongoing. That’s all I’m going to say about that.”

“It’s possible,” she responded to a second query about whether her children support the Brooklyn-born, Vermont senator.

McCray and de Blasio are both supporters of Hillary Clinton, but younger, Democratic voters are skewing more toward Sanders, polls show.
