MILWAUKEE — Democratic Socialists of America revamped its platform ahead of a national summit this weekend in Chicago, shifting some official positions on immigration and democracy, as Republicans try to cast the entire Democratic Party in its mold ahead of the midterms. The subtle changes to DSA’s agenda come as the organization, which has surged to more than 120,000 members, faces a brighter spotlight than ever. “I’m all in on Wisconsin, and so the platform that came out from DSA national is less of a concern for me.” On Friday, when Fox News host Dana Perino asked Hong what parts of the DSA platform “you disagree with,” she cited abolishing the Senate — though in 2021, she tweeted “abolish the Senate.” “I would say that defunding the police is the opposite of democratic socialism,” she said.
