Because aside from his record and the fact that his policies would have been the most beneficial to black people, a Bernie Sanders, universality type platform is the ONLY way we will ever get anything close to reparations. Cacs will lie down in the middle of the freeway before they support black people getting some kinda check they can't get.
But if you focus on economic freedom and equality for EVERYONE in exchange for specific policies on top of those GND, UBI type programs, you could even get rural people to get behind 'common good captalism' that nets them free college, healthcare, basic income, marijuana legalization and even fukking functional wifi in some places that still don't have it out in the country, which was a lesser talked about idea that Bernie was pushing for. Tacking on things like tax exemption, marijuana industry grants ect for FBA's would be the easiest way to gain some real footing to take that even further.
When the right goes all in they get Trump. When the left goes all in, they get the new deal and elect a 'progressive' president so many times they had to create term limits. And seeing how we were left out of the OG new deal, we should re-up on that and prioritize black folks in the process.
I fukk with Bernie, I mostly respect his voting record, but he is/was only a means to an end.
