A recent poll suggested that, even among Hillary voters, Bernie wins out in popularity. (As well, a different poll suggested Bernie supporters were more progressive on race issues than Hillary supporters). Most Americans support and like single payer. And most people in any form on the left have pretty similar progressive views.
The writing is on the wall. The type of policies and positions that Occupy people, Sanders support are very popular. People really really dislike moneyed interest in Washington. And that is probably where the
biggest contradiction was in Hillary's platform. When she went around saying that campaign finance laws were broken, because moneyed interest has undue influence on politicians and elections, yet also claimed to not be influenced by that same financing. It was internally contradictory. But people see someone like Sanders, with all of his faults, and at least see something different, some hope and promise. Again I really don't want to glorify him personally too much, because really he's just a man and is flawed. But I also feel there's some real hope in the political movement that surrounded him. I don't really care to see him run in 2020 but I hope that same sort of movement will happen again. However:
So, you say, you don't meet people who believe that way. That's fine, I don't come across them often myself. The problem is, the people who
do believe that are the people who are most influential in the Democratic party: the same people who buy "Hillary beat sexism" children's books are the same people voting in the primary, the same people who accuse Sanders of costing Hillary the election are the people preparing the party for 2020. These Clinton apologists
aren't your everyday people, they're often privileged, bubbled white people with a outsized influence in politics. And they will very likely be the primary voice of any leftward movement in the coming years, where the stakes are much higher than they have been previously (and I don't mean that hyperbolically, I believe the United States is at a tipping point in terms of global power and economics). But the leftward shift in people's sensibilities will march over Clintonites and leave them in the dust if they don't fight, they're entrenched in privilege and power and don't want to surrender it for anything.
