Noncitizen voting in federal elections is already illegal. The SAVE Act doesn’t fix a real problem; it creates one. It builds a giant bureaucracy to hunt for rare cases and ends up blocking huge numbers of eligible citizens who did everything right. #sheshed

How did we get to the longest oligarchic retrenchment in America’s history (e.g. now)? How did ‘movement conservatism’s’ rhetoric, ideology, and misinformation campaigns of the past ~45 years bring us to this point? And where do we go from here? Dr. Richardson illuminates our history and future.

Speaking diplomatically when the person you’re talking to is not basing anything they ‘think’ on actual facts and reality IS somewhat crazy-making. I only try so hard, after that you have to call it off and tell them when they want to deal in reality, you’re there for them.

This really spoke to me
The trick is maintaining a sense of alarm that doesn't tip over into despair (and at the opposite end, not falling into complacency "it will all work out" or "that's someone else's job to make it work out). We are in the middle of the story and we write it with how we show up, how we build solidarity, how we support those in the front lines, how we stand on principle, how we don't let them erase those principles of truth, fact, law, science, and human rights.
