Respond to any dipshit arguing "violent BLM rioters" contributed to this defeat by making the Democrats look bad by telling them that the spontaneous reaction of average, working people to events that are directly caused the systemic failure of bourgeois governance cannot be controlled or managed for electoral purposes. Electoral entities and candidates can only respond to this spontaneous anger, using it in whatever way for their own political purposes. The riots didn't "undermine" the Democrats, the Democrats undermined themselves by failing to either preemptively resolve the institutional problem of police brutality or by reacting to the backlash against that issue in a strategically poor fashion. Both are correct.

This is a symptom of the lib cope response to this cycle that boils down to "The Democrats didn't fail the American people, the American people failed the Democrats". The largest turnout in a century, against a party whose agenda overtly enshrines minority rule and suppresses turnout, and they STILL FUCKED IT UP
