not gonna bother watching the video, but it's not secret why the Dems keep losing. They are so beholden to their big donors, wealthy libs that are big on identity politics and culture wars, but are terrified of the class war. They would rather lose than allow a nominally "socialist" like a Sanders to take reign. This is not even new, they did to Sanders the same they did to Henry A. Wallace, and they'll continue to do it for their wealthy donors.
