In the same month, 15 members of the DSA were elected to various local and state governmental positions around the country in the 2017 elections. Tracing its lineage from the New Left to Norman Thomas and Eugene Debs, the DSA was the largest Socialist organization in the United States by 2017. As of September 2018, membership stood at 50,000, and the number of local chapters had increased from 40 to 181. In June 2018, Alexandria Ocasio-Cortez, a member of the DSA, won the Democratic primary in New York's 14th congressional district, defeating the incumbent Democratic Caucus Chair Joe Crowley in what was described as the biggest upset victory of the 2018 midterm-election season. She was elected to the House of Representatives in November 2018. According to Gallup, socialism has gained popularity within the Democratic Party. As of 2018, 57% of Democratic-leaning respondents viewed socialism positively as compared with 53% in 2016. The perception of capitalism among Democratic-leaning voters has also seen a decline since the 2016 presidential election from 56% to 47%. 16% of Republican-leaning voters and 37% of American adults overall had a positive view of socialism in the 2018 poll, compared with 71% and 56% holding a positive view of capitalism, respectively. A 2019 Harris Poll found that socialism is more popular with women than men, with 55% of women between the ages of 18 and 54 preferring to live in a socialist society. A majority of men surveyed in the poll chose capitalism over socialism. A 2019 YouGov poll showed that 70% of millennials would vote for a socialist presidential candidate, and more than 30% think highly of communism. A 2021 Axios poll found that 41% of all US adults have a positive view of socialism, up from 39% in 2019. On April 2, 2019, four members of the DSA won run-off elections in Chicago while two others retained or won their seat in the February election, bringing the total number to six socialists on the council. Socialists control twelve percent of Chicago's city council power which Jacobin managing editor Micah Uetricht states in The Guardian that it is further evidence of a "socialist surge" in the United States and "the largest socialist electoral victory in modern American history." At the start of the 2021-22 legislative session, the New York State legislature had the most self-identifying socialist members in over a century. DSA-endorsed candidates Zohran Mamdani, Marcela
