I have no solution except impeachment and indictment
You get that this is functionally no solution at all, right? Even in Obama’s first term there were only 60 Democratic-caucusing senators and a few of those were unreliable DINOs. 67 is a fairy tale. It’s only marginally more likely than just hoping they get raptured.
And if that’s the case, which do you prefer:
Living the rest of your life under a conservative court making up law as it goes.
Legally changing the size of the court as has been done before, but in the process breaking precious norms.
