TERRY GROSS, HOST:

This is FRESH AIR. I'm Terry Gross. American socialists are having their best year since 1912. In last week's midterms, six socialists were elected to Congress, and three were elected mayor, which means New York, LA, Washington, D.C., Seattle, Ann Arbor and Providence, Rhode Island, are now led by socialists. But socialism means different things to different people. Even among American socialists, then and now, different factions have serious disagreements over what the agenda should be.

My guest, Jill Lepore, has written about the history of American socialism from the founding of the Socialist Party of America in 1901 to today's DSA, Democratic Socialists of America. Her new article in The New Yorker is titled "Can American Socialism Survive Its Success?" She's also recently written about whether the president has the power to declare war and how difficult it is to be a historian in a period when President Donald Trump is trying to rewrite American history and deleting its darker parts in schools, national parks and museums.

Lepore is a professor of American history at Harvard University, professor of law at Harvard Law School and a staff writer at The New Yorker. Her books include The New York Times bestsellers "These Truths: A History Of The United States" and "We The People: A History Of The U.S. Constitution," which won a 2026 Pulitzer Prize. Her latest, "The Rise And Fall Of The Artificial State," is about how AI is affecting politics and government.
