It's less at this point that I think he will hurt Clinton (though there is still a non-zero chance) and more that all his recent public-facing actions are those of a man who seems bitter, delusional and clearly not doing everything he can to prevent Trump from winning. It's a validation of literally everything Barney Frank and anyone who has ever been critical of Sanders has ever said. It's........weird and not in a remotely good way.
But Trump has next to no chance of winning regardless, thus Sanders picked the wrong time to pull this stunt. The board is already set. I get the impression he thought Hillary would struggle against Trump and come begging to him for help. Instead she's crushing him, republicans are in disarray, and she has multiple surrogates who are better than him (Obama, Warren, Bill).
And this is the guy people thought could create a political revolution. He's terrible at politics. Now he's running around trying to destroy the president's signature trade agreement. It doesn't make any sense. But ultimately it doesn't matter. He's finished politically and is just enjoying his final moments. I have no problem with that.
I checked his reddit and saw a thread about how his supporters aren't even phonebanking for the couple candidates he has endorsed. There is no political revolution, this was always just about Bernie Sanders.
