Working to stack the Supreme Court, and triggering a constitutional crisis in the process because the Republican Senate will refuse confirmation, and the Supreme Court that was stacked with self-contradictory GOP bullshit will agree with them would be the interesting move that won't happen because the Democrats are cowards and institutionalists rather than fascist monsters.
But that would shift the election in favour of the Democrats...
