You dance with the one what brung ya

I’m at a loss about what the 30% campaign is even trying to do at this point:
Amid this parade of support at a Flint town-hall-style event on Saturday night, Mr. Sanders looked on, largely silent — at least when it came to wooing the black voters whose strong backing of a rival candidate could once again cost Mr. Sanders the Democratic presidential nomination.
Sanders campaign aides had billed the event as an opportunity for him to make a case directly to black voters for why they should support him over Mr. Biden. But the audience ended up being overwhelmingly white, and Mr. Sanders made so few overtures directly to black voters that the event seemed unlikely to pull large numbers of African-Americans away from Mr. Biden.
Mr. Sanders’s relative silence was deliberate, those involved in the event said. The guest speakers — several of whom were flown into Flint by the campaign — decided before the event that it would be better to let them discuss the issues affecting their communities than the man running for president to represent them.
Mr. Sanders opted not to deliver the speech that he had spent much of the day crafting, according to aides, who declined to describe the message he had hoped to communicate.
It’s like a coach who attains a modest level of success with a system that works in a particular context, and then insists on playing that system long after other coaching staffs have figured it out and it makes no sense for the available talent.

Once it became clear that Biden — Biden! — was the best hope of the mainstream wing of the party, it was Bernie’s nomination to lose. And boy did he.
