Pack the Supreme Court, make the Reps bitch and moan about it.

Why wait?

I don't even care if it ends up holding, or even working at all, but we need that 'Lyndon Johnson cockslaps you in the bathroom' kind of energy.

Oh, the Reps want an actual law that caps the Court? Sure, if you kill the Electoral College.

See, you can just assert your own framework of negotiations, instead of just taking whatever the Repulicans lay down as their terms, and then working within those.
