In November 2015, hundreds of students stood in the rain at Georgetown University, hoping to hear a presidential candidate named Bernie Sanders. When he finally spoke, he summed up his vision with two words that most Americans had never heard applied to politics: "Democratic socialism." At the time, the Democratic Socialists of America (DSA) had only 6,000 members, with an average age over 60. Sanders himself was not a member. But people Googled the term, started joining, and after Donald Trump won in 2016, membership surged.

Michael Harrington grew up in a devout Irish Catholic family in St. Louis. His mother hoped he would become a priest.

The Democratic Socialists of America (DSA) is having a big moment. Its candidates and its membership are both surging. Before Zohran Mamdani and AOC, there was its founder, Michael Harrington, a.k.a 'the man who discovered poverty.'  In this episode, we dig into Harrington’s evolution from devout Catholic to revolutionary socialist to Democratic party loyalist, and ask: did his push to compromise delay the dream or pave the way for it?
