While I'm not resting my position on the statements of these few guys, this exemplifies exactly why I think leftist Dems like Sanders and Warren have the best chance at defeating both Trump and Trumpism. The working class (all races thereof) is not scared to vote for soaking the rich and big government programs that help them. They want that shit if it is the real deal. Plenty in the middle class do too. The problem is that Dems got scared by the Reagan messaging machine and gave up this mantle starting in the 80s and 90s. The Dems became R lite with a socially liberal frosting. R policy after R policy got enacted — often by Dems themselves! As income inequality, health care costs, and other similar problems skyrocketed, nobody was making a real difference for lower income folks.
Trumpism (starting well before Trump himself) came along into that vacuum and said, what have Dems actually done for the working class or middle class? What have they done about all of the problems you're actually facing right now? And without any good answer to hold it together, it was easy as pie to wedge the working class apart by race.
There needs to be a cohesive ideology on the left to counter the racist message of the right. The only ones I see offering that are Warren and Sanders: the problem is that the corrupt government works for the rich and nobody else, and the solution is to tax the rich to fund big beautiful government programs.
Centrist Ds and Rs will recoil in horror, just as they recoil in shock every time they hear things like "actually, plenty of union folks would rather have government insurance than their bargained-for private plan," or "actually, the Green New Deal isn't a joke, and can even appeal to coal workers." But that's what will win. More importantly, that's what will actually help people who are in need, and make the wins last past just one or two elections.
