his voter base is people of color, wtf are you talking about? That's helping him.

He just represents novelty and anti-establishment values like talking about the problems of working class people, in the same way Trump does, but he does that without appealing to fear or hate. That's it, that's why he won. The rest is just ornamental. He defines himself socialist to get traction and participation among volunteers, but for the voter base, that's not helping him.
