it will happen easily if biden wins. If the court majority becomes 5-4 liberal republicans will absolutely hop on board. Thats why dems should also float an electoral college reform and an amendment to ban gerrymandering. Even a ban on courts creating “immunity rules” should be floated since immunity is something that shouldn’t be handed out as often as the supreme court does it.
The amendment process is long and difficult and honestly being just willing to go through the extra steps makes good headlines.
