Four years later, Bernie Sanders and his top supporters suffered from the same blindness. They had a BS narrative of their own: (1) There will be a massive turnout surge from disaffected Sanders voters (BS); (2) The Democratic party’s progressive Twitter wing had upended the establishment over the past four years (BS . . . and kinda crazy BS, at that); (3) Look at the crowd sizes! (4) Younger latino and black voters will go big for Bernie and either offset or convince their parents (lol); and (5) Biden is sundowning and doesn’t have any support (this BS was built on other BS—meaning Twitter and crowd size).

It was this narrative that drove many of the decisions the Sanders campaign made. And it blinded them to the possibility of other outcomes.

After Sanders won big in Nevada he had a golden opportunity to show he could unite the party and take on Trump. But he didn’t budge an inch from his insurgent, doctrinaire democratic socialist stance. When asked about his past comments praising communist dictators, he couldn’t even bring himself to denounce them without caveat and, in the process, demonstrated that he cared less about winning than in freebasing 100 percent pure, uncut Bern.
