A strange new gender politics is roiling the 2024 election. At the Republican National Convention, Donald Trump made his nomination a show of campy masculinity, with Hulk Hogan, Kid Rock and Dana White, the president of the Ultimate Fighting Championship, warming up the crowd. JD Vance’s first viral moments have been comments he made in 2021 about “childless cat ladies” running the Democratic Party and a “thought experiment” assigning extra votes to parents because they have more of an “investment in the future of this country.” Meanwhile, Kamala Harris is centering her campaign on abortion rights, and Tim Walz has been playing up his own classically masculine profile — as a former football coach, hunter and Midwestern dad.  What are the two sides here really saying about gender and family? And what are the new fault lines of our modern-day gender wars? Christine Emba is a staff writer at The Atlantic and the author of “Rethinking Sex: A Provocation.” Zack Beauchamp is a senior correspondent at Vox and the author of the new book “The Reactionary Spirit: How America's Most Insidious Political Tradition Swept the World.” In this conversation, we discuss some influences on JD Vance’s ideas about gender and family, the tensions between those ideas and the beliefs about gender represented by Donald Trump, the competing visions of masculinity presented by the two parties in this election, how Dobbs changed Democrats’ message on gender and family, and more.
