The entire point for these people should be that the milquetoast shit Bernie proposes is actually *just as impossible* as nationalizing Amazon, setting minimum wage on imports, closing all military bases. Can't just say electoralism is pointless and have people take it on faith.
That is, if you believe in that line. I'm no longer really sold on it as the years wear on and EU social democracy remains largely in place where it developed. And where they still have left currents.
