Any progressive could come out right now and pin this loss on the establishment democrats, potentially setting themselves up to be a front runner next election cycle. 

The only person I could even imagine doing something like that is Rashida Tlaib, but I doubt she will. Democrats have no future. Need a workers party with maybe Shawn Fain or the other guy I can't remember his name leading. 

 They better start denouncing zionism left and right to gain any kind of credibility back.  

 Zero chance of that happening.
