Worth the read. I don't go quite so far as the author in thinking that these failings arise from malevolence on behalf of Sen. Sanders; however I do think that his self-awareness looks like it's failing somewhat in the face of his success and ambition.
In particular; the stupid, self-destructive claim that Sec. Clinton is somehow "bought and paid for" has to end. It's a lie, propagated endlessly by her GOP opponents for cynical, self-serving ends. I'm appalled at my comrades on the Left, so normally inoculated to be suspicious and dismissive of reactionary propaganda, who are falling for it hook, line and sinker.
