On March 6, 2016, at the height of her presidential campaign, Hillary Clinton or someone on her campaign posted a tweet about intersectionality. Commenting on the water crisis in Flint, Michigan, the accompanying diagram depicted the various issues that had intersected to cause the crisis. This was a curious moment, as a theory with roots in radical feminism was brought to the center, part of a modish interest in intersectionality as an explanatory framework for understanding contemporary America. Indeed, where her main primary challenger was positioned as a more economically progressive choice, Clinton’s supporters often claimed (with varying degrees of sophistication) that in an intersectional sense she was the more properly anti-establishment candidate, over the white male Bernie Sanders. Had Clinton won in November, this discourse of intersectionality would probably have been a main theme of her presidency. That this seemingly centrist liberal set of ideas can be traced to the radical wing of second wave feminism, the New Left, and even Marxism, adds to the curiosity of its move to the political mainstream.
