Not really. Obama notoriously destroyed his entire political apparatus once it had served his purpose, then let the Dems lose over a thousand state level seats across the country. Hillary operates a patronage network of absolute ghouls. Most Dem politicians have a grip on power they won't relinquish this side of death.

The party isn't really a party, it's thousands of vaguely ideologically aligned self-serving individuals united entirely on the basis of not being Republicans. There's no real leadership, no one is developing a new generation to replace the old, there's no coherent ideological goal beyond more austerity and more war. There's little or no meaningful grass-roots participation; Dem political candidates are chosen almost entirely on the basis of how much money they can raise through the Democratic patronage networks. Most of the Dem voters have no idea about any of this. I don't think many of them even understand what a real political party is.
