You don't understand. The party that packs the court should have enough votes to make sure they never lose power again. If the party in power packs the court, what's going to happen is the other half of the country will just declare the federal government illegitimate and form their own.

The reasonable end game is probably something like justices with term limits, or a fixed number of appointments per presidential term.

We probably will never get there without having to play stupid political games in the meantime, given the state of our political parties.

Which is why they are pushing to make DC the 51st state in tandem to ensure that doesn't happen.

One of the many reasons it's a stupid idea.
