I really think it's the DNC being an ideological void trapped in the end of history. There's nothing for them to aspire too, no better future to build. Their world doesn't allow it. All it allows for is crooks and grifters to chase influence and power, they have nothing to build a coherent identity or philosophy around. They cannot plan for a future because for them there is no future./ Or maybe thjey're just fucking idiots.
