The problem with almost any solution to the current system is that it requires the people who benefit from the current system to allow it.
but the point is you have to want to in the first place. IF we did have the votes many if not most liberals still wouldn't approve of the tactic. In my view it's a basically conservative, even reactionary impulse. They think they're protecting some kind of hallowed institution or something, but it's just a "West Wing" fantasy, and it only serves to act as a bulwark against democratic pressure. And now they find themselves in an almost laughable paradox, because the whole purpose of preserving the pristine SCOTUS was to avoid Republicans taking control and doing something like overturning Roe. Yeah... it'd be a real shame if that happened, huh?
