Last week, two Democratic Socialist of America members achieved successes in primaries, thus being selected to replace long serving Democrat representatives. These victories, and others, underscore the left movement’s growing ability to outcompete the party mainstream. In Maine, Graham Platner, who has described himself as a DSA member in online forums, clinched the nomination for the US Senate, besting the party’s preferred candidate, Gov. Janet Mills. On the other coast, Nithya Raman, the first DSA member elected to the Los Angeles City Council, advanced to a mayoral runoff against the establishment-backed incumbent, Karen Bass.
