There are systematic reasons why Bernie (again) wasn’t able become the nominee, and I believe these reasons will apply to anyone with similar views trying to become a Democrat nominee. The party doesn’t want SocDems to be their leader.

I don’t think that’s nihilistic. But it is rejecting the electoralist approach as futile for people who want Bernie’s policies in the USA. We must look at other ways, established ways of moving forward and bringing progressive change. After the past two elections, insisting that Bernie or AOC can win the nomination next time, being in denial of how the Democrat Party works, is not just unhealthy discourse but counter-progressive in practice.
