One thing the far-right Supreme Court has learned well, that Democrats in Congress would have done well to learn (it's probably too late now), is a lesson from Machiavelli about exercising power. To wit: if you feel compelled to take certain actions that you know are unpopular, or will engender backlash -- do them all, do them early, and do them all at once.
From abortion, to guns, to climate change, to funding religious schools, to prayer in school, to Indian sovereignty, to racial gerrymandering, the Supreme Court delivered an orgy of far-right fantasies over the course of barely a week. Liberals are furious. How could we not be? But we're also reeling. How could we not be? If a few of these decisions came out the other way, would we be materially less furious? Unlikely. If the decisions had been spread out, would our rage be dampened? No, if anything it would have been reignited anew each time.
The Supreme Court acted decisively and without remorse. Its response to any notion of moderation or gesture of even-handedness was an enthusiastic middle finger. The strong take what they may, and the weak suffer what they must. Not exactly ideal behavior from a court, but for those who see themselves as princes -- well, Machiavelli would be proud.
And in turn, failing to follow this advice is the mistake Democrats made over the past two years (and of course, we can lay blame primarily at the feet of Synema and Manchin here, with some assist from the "Problem-
Solvers Causers Caucus"). Democrats needed to do big things. Those things would be controversial. Talking them out indefinitely in a bid for a compromise that would never occur only would bleed resources (ask Barack Obama how that went with the ACA). Better to slam them through at the start. Voting rights, anti-gerrymandering, DC statehood, BBB, protecting abortion rights. Yeah, these things would be controversial. They wouldn't be any less controversial if they're spread out in drips and drabs. Do them all, do them together, weather the storm, and then spend the rest of your time consolidating your position.
Alas, now its probably too late. This may be why, even after literally everything that's happened, if there was a single item I could slam through Congress before the turnover it'd be DC statehood. It's not necessarily more important than other candidates -- though DC's status as an American colony is a moral disgrace of epic proportions -- but it'd make it more likely Democrats would hold Congress through 2022 and so could try again next time. Democrats having power is not a sufficient condition for reversing these terrible trends, but it's a necessary one. It's hardly guaranteed they'll learn their next time around; but we'll never find out if there never is a "next time".
