In a few years (after the 2020 election) there will be a thing called the Democratic party, but it won’t be run by these self-described “progressives” anymore. I think the battle is beginning now to figure out who is going to run it.
The DNC selection process for their new leader seemed to reflect that.
I don’t know much about the guy they wound up with, but I note they didn’t go for the obvious problematic guy. (this other one may be too though)
