Reminder that we won't actually know what happened for at least a couple weeks. Maybe third party voters & "genocide Harris" leftists cost us the election, but I think we should also keep space for the idea that Americans' culture of individualism means they often vote for their own personal interest, and the economy is always a top motivator for which way people vote.
Of course third party voters & "genocide Harris" leftists fucked up, but general American stupidity might be mostly to blame here.
Anyway, check out MoveOn. They're a large organizing force, and I've phonebanked with 3-4 different groups through them, including Indivisible Illinois.
