After Super Tuesday, Bernie Sanders’s campaign for the Democratic presidential nomination has reached a critical point. Many voters have bought into the Clinton camp’s aura of inevitability, while others feel there’s still a fighting chance. But wherever the campaign ends up, socialists agree that the real work lies in building permanent, independent political alternatives for working people.

What they have not agreed on is how to build that alternative and whether directly supporting the Sanders campaign helps in this goal.

In December, four socialists came together to debate these questions. Danny Katch of the International Socialist Organization, Bhaskar Sunkara of Jacobin magazine, Gloria Mattera of the Green Party, and Dustin Guastella of the Democratic Socialists of America each offered their viewpoint on how to relate to the campaign and — crucially — what to do after it ends.
