What the fuck
Why is this SO long and consists only of "fuck the Democrats / the Democrats betrayed us / be disheartened / fuck the Democrats / the Democrats betrayed us / be disheartened"
Like I try to imagine Martin Luther King or Eugene Debs giving this as a speech, and I can't imagine it. "There's no winning. Let's all remember the bad times and cling to them like they are our only harbor in the storm. Let me catalogue the times people failed us, volume 1" (although with more heat applied to it than specific examples).
If you want a more coherent and productive version of this, that talks about how to actually push the Democrats to the left instead of just instigating a personal depression-crisis about the state of American politics (which although sorta understandable is not a productive way to get better outcomes), this interview with Ralph Nader might be a good place to start.
