The Democratic Socialists of America are meeting there this week as part of the group’s biannual convention. In the wake of a surge of new interest over the past year, the organization announced earlier this week that it now has 25,000 dues-paying members — a historic peak for the group that makes it the largest socialist organization in the country since World War II.

David Duhalde, DSA’s Deputy Director, was brought on by the organization in 2015. He told The Intercept that shortly before the November election, the organization had between 7,000 to 8,000 members. On November 9, they started seeing supporters of Vermont’s Sen. Bernie Sanders’ presidential run and others flooding into DSA.

“We have come from, I would say, being a very well-intentioned socialist organization of people who primarily knew each other,” he told The Intercept, laughing, “to a really burgeoning mass organization of people who are nationally oriented.”

The 800 elected delegates to the convention busied themselves with answering questions about what the organization will do with its growing membership in the post-Sanders campaign world. They are spending the weekend debating and passing resolutions on issues ranging from whether to endorse and support the Palestinian-led Boycott, Divestment, and Sanctions (BDS) movement to the best way to recruit and organize more Americans from ethnic minority groups into the democratic socialist movement.

Harold Meyerson, who serves as the editor-at-large at the American Prospect and a columnist at the Washington Post, has been a member of the DSA since 1975. The surge of new members has lifted his spirits. As a long-time socialist who worked in establishment organizations, his moment has finally come. “It’s been so transformed,” he told The Intercept. “For the first time since the ’30s, there’s really an anti-capitalist if not necessarily socialist groundswell in the country.”

Polling done earlier this year by the American Culture & Faith Institute found that 37 percent of American adults now say they prefer socialism to capitalism. Among millennials, the divide is even sharper. A Harvard University survey taken last year found that 51 percent of respondents between the ages of 18 and 29 no longer say they support capitalism.
