This summer, the Democratic Socialists of America have mounted their biggest and most successful attempt yet to redefine the Democratic Party. They have defeated its candidates in primary after primary from coast to coast. As its electoral success grows, the organization is confronting big, unresolved questions about what it stands for and what level of compromise is required to become a lasting political force. Charles Homans, who talked to more than 30 D.S.A. candidates, organizers, members and volunteers across the countries, discusses the rise and limitations of the D.S.A.  Guest: Charles Homans (https://www.nytimes.com/by/charles-homans) writes about national politics for The New York Times and The Times Magazine.
