The Left is disenchanted with our country, and especially its governing institutions, which it believes are shot through with racism and deeply undemocratic. Democrats have gone from assuming a few years ago that they have a permanent majority to assuming that they can’t possibly win under such a rigged system.
They no longer want to live under a government that checks majoritarian passions, recognizes the importance of states in our federal system, and features a Supreme Court that is supposed to render independent judgments based on the law and the Constitution. All of this, once a matter of basic civics, is now for suckers.
Before its new fashion, court-packing used to be notorious, the ill-considered move that FDR couldn’t see through even at the height of his power.
