Every single day will bring defeats like this one until Biden packs the Court or removes the corrupt justices. He can do either immediately, using the umbrella of "immunity" they've cast over "official acts."
Not really. The immunity protects him from criminal prosecution after leaving office, but court-packing requires an act of Congress to create the new seats.
What Dems should be doing right now is laying out their legislative agenda for reforming the court, but it seems like they can't be bothered.
