Bernie is a centrist at best. Things like civil rights are bare minimum, I’m talking about fundamental workers rights like the right to unionize, repealing Taft-Hartley, setting up matching programs with unions so that they can buy up their companies and become worker cooperatives, etc.
I believe Bernie is more based than centrism in his real views, but his public views are centrist at best.
He exists to deal with the revolutionary energy that is building and make people feel like their voices are being heard under the current establishment. But the reality is that you need corporate backing to win an election in the US by design. It is a corporate oligarchy, not a democracy
Those are all great in the context of US politics. But things like universal healthcare shouldn’t even be part of the debate, they should just be the standard expectation.
