The SCOTUS case decides nothing except for which side is the union and which side is the confederacy
Favorable Ruling: Dems effectively secede.
Disfavorable Ruling: Since states can't be held accountable for their own laws based on the constitution, states can secede.
No Ruling: Try again at military tribunals.
OK, yes. I had heard that, am actually learning this stuff from the other side of the pond. So, The choice is alienate your entire electorate, or piss off the Thieving Democrats...
