The leftist Democratic Socialists of America, which helped congressional star Alexandria Ocasio-Cortez get elected in 2018, looks to be a big political player again in New York City’s 2021 municipal elections. The group has not yet endorsed anyone for mayor – the top prize in New York’s June 22 Democratic primaries. But all 51 city council seats are up for grabs this year, and the DSA has members running for six of them – including Queens public defender Tiffany Cabán and Brooklyn tenant activist Michael Hollingsworth. With two state senators and five representatives out of 213 lawmakers, the New York State Legislature already has the country’s largest DSA legislative caucus. These Democrats share a leftist platform that includes guaranteeing housing as a human right and ending mass incarceration The DSA has upended local politics in this Democratic stronghold, and its wins extend well beyond New York – into Virginia, Nevada and beyond. How did socialism jump from the fringes of American politics into its very center?
