I'm not sure, but I will say that the absolute guaranteed cakewalk victory for Hillary is far much less of a certainty after last night, which was pretty much a condemnation of "New Democrat" politics.
This should be as much of a condemnation of the pro-Wall Street politics of the party establishment as 1894 was.
There is no indication that the democratic establishment wants change. The midterm electorate wants to vote for an even more pro-Wall Street party and the democratic primary electorate is no threat to the establishment. If they need to be thrown out for progressives to make a come-back, we might as well dissolve the party.
