Further, neither side (seems to) accept incremental change and loves making the perfect the enemy of the good -- especially, imo, the left -- so they get nothing and complain about it.
You're going to have to elaborate on that one, considering that the ACA came from the Obama administration and was about the smallest incremental change possible. Not that republicans didn't try to repeal it several times anyway.
Sometimes incremental change happens, like the ACA, sometimes people go all accelerationist[0]/Bernie-or-bust on us and then someone vastly worse[1] gets elected. Seems like it's more the latter than the former these days considering how divided we are, politically.
