Hillary Clinton seems poised to become the first woman to be the presidential nominee of a major American political party. It’s supposed to be a major symbolic moment, at least in terms of identity politics. But it feels hollow, largely because of something most commentators hesitate to say in public: if she hadn’t married Bill Clinton, she wouldn’t be where she is now. Why can’t a nation of 319 million people find a woman president who didn’t marry her way into the job? Because the system still won’t allow it.
