Do you consider Sanders to have been a good candidate? The 'bad' candidate crushed him. I'm amazed how many Sanders supporters have convinced themselves he was such a great candidate and somehow he lost by millions of votes because the DNC said something mean about him in an email instead of just recognizing that he didn't appeal to large swaths of the Democratic coalition.
That's a rather self-serving way to spin history. First, it's obvious the DNC bias had some effect on primary results. For example, it spun up an army of faithful drones armed with DNC talking points to attack Sanders. More importantly, however, Sanders mostly took the high road with Clinton. Unlike the RNC, he did not drag Clinton through the mud. He did not hammer her incessantly on her character and scandals. Had he been more aggressive and more negative, it may well be that Sanders would have "crushed" Clinton. Sanders' civil campaign was good for Clinton in the short term, but left her more vulnerable in the general.
I remember Hamilton Nolan at Gawker being angry and baffled as to why black people weren't flocking to Sanders because he somehow didn't realize they didn't give a shit about student loan forgiveness. I also remember going to a Sanders rally in Prospect Park and seeing that there were basically no black people there despite the park being surrounded on two sides by heavily black neighborhoods.
In an election the Democrats lost in large part due to lesser black turnout let me register my doubt that nominating the guy almost no black people voted for would have helped.
Yes, but the Democrats didn't just lose because of low black turnout. They also lost because millennials and independents didn't turn out for Clinton. Sanders had strong support in both groups. There are several people here, and several friends and associates I talked to personally, who said they respected Sanders and would have voted for him, but absolutely hated Clinton and would not vote for her. Period. Might they have made the difference for Democrats? We will never know.
