The American far-left refusing to enter partnerships and engage in strategic bartering with their analogous in the dominant two-party system will doom any chance they have to wield actual influence influence over politics and policymaking at a national scale. https://twitter.com/demsocialists/status/1249351571831435269

And again, I think it’s a deeply unserious attitude that not participating in the political system at all is better than supporting a deeply flawed but proximate candidate in a two-person race. Why sacrifice all your agency when there is still a preferable outcome on the table?

I will say that Sanders and his closest allies seem to understand these tradeoffs. Of course, Sanders has been fighting this battle for 40 years in Congress, so we should expect him to know better than DSA types how to actually achieve political goals.
