During an interview, New York Magazine reports Bloomberg said the following in an exchange with the mag:
NYMag: Then there’s Bill de Blasio, who’s become the Democratic front-runner. He has in some ways been running a class-warfare campaign—
Bloomberg: Class-warfare and racist.
Bloomberg: Well, no, no, I mean he’s making an appeal using his family to gain support. I think it’s pretty obvious to anyone watching what he’s been doing. I do not think he himself is racist. It’s comparable to me pointing out I’m Jewish in attracting the Jewish vote. You tailor messages to your audiences and address issues you think your audience cares about.
According to NyPo, De Blasio is married to a black woman and has two bi-racial children – one of whom, Dante de Blasio, has figured prominently into his campaign.
