IMO, the best chance to get Bernie 2.0 any time soon (i.e. not 20-30 years from now) is to get Bernie 1.0 in the White House.
I'll support Clinton if she gets the nomination but I won't cry if/when she loses. I think she is a deeply flawed candidate.
What's probably going to happen is she will win and in 8 years it will be Castro running saying he will continue the same policies as Obama/Hillary and you will see the same people come out and trot the same arguments about electability and the supreme court.
I don't think so.
I think that the changes to society and the ideas that are gaining popularity and are becoming widespread today ensure a Bernie 2.0 will appear in the future, no matter whether Hillary wins the nomination or not. If you think of this as a war, then now is the time to secure tentative gains and fortify said gains. If she becomes president the job of Hillary is to be a wall, and bide the time for more demographic change. If the youth vote is so clearly energized and ready to participate in politics, then yes, you won't have to wait 20-30 years from now to get Bernie 2.0 in the presidency, because said vote would be enough to get him or her the Democratic nomination maybe even 8 years from now.
But right now it's obviously not enough. There's not enough demographic change. And Bernie is a poor candidate in the sense that he picked one strategy with very little deviance. It's not enough to pull enthusiasm or support for him from anywhere other than youth. And I guess white men.
You might think of it as "I've done this compromising thing for a long time, I'm tired of it"but I see that as something of a selfish desire for instant gratification. For the whole process, I think of it as a long game. The idea isn't to get immediate satisfaction; the idea is to cement change and push for more working with the system. If it is a game of inches, so be it! Most of us who are posting here bitterly complaining? We're the young and the future, and we'll be here as the older, conservative voters die out. We have time. With Hillary we can address the urgent concerns (Supreme Court), defend recent gains (Obama), build for the future (DNC down ticket collaborations/elections) and what is so wrong with that? Because progress takes years and more than one person's effort?
