In her concession speech to U.S. President-elect Donald Trump in November 2016, Hillary Clinton declared, ¡°We have still not shattered that highest and hardest glass ceiling, but some day someone will ¡ª and hopefully sooner than we might think right now.¡±

There was lots of talk about gender in politics then. Many of us thought that Clinton lost in part because of hard-core misogyny and a softer unconscious bias that led just enough voters to think of presidents only as guys in suits.

I¡¯ve been thinking lately of that glass ceiling because of a conversation we¡¯re not having ¡ª one about the gender of the Democratic nominee if Joe Biden takes advice from so many of us to drop out of the presidential race.
