It started out with a soft launch: a snippet of Dante de Blasio supposedly giving his father some tongue-in-cheek advice before he stepped on the presidential debate stage. It did not land particularly well.

Then he published an op-ed he had written a few years earlier about his interactions with the police as a young black man, and how his father, Mayor Bill de Blasio, instructed him to be cautious.

Now, Dante is ready to pitch in full time: He is joining the de Blasio presidential campaign as a paid policy analyst.

“I’ve always loved politics, love learning about it, love being involved in it, and this campaign seemed like a great opportunity to get more involved in the world,” Dante said on Friday at the de Blasio 2020 campaign headquarters at The Yard, a shared working space in Gowanus, Brooklyn.
