Mark me down as skeptical. If you believe leftist judges are going to honor that agreement. that is your right. But O-care itself rode in on a wave of dishonest promises.
And I'll join the chorus of conservatives who know that Obamacare was the product of deception, distortion, and outright lies.
As for future SCOTUS decisions, well ... you're right, a courtful of Sotomayors or Ginsburgs could not be trusted to adhere to stare decisis when it comes to anything, especially the 2nd Amendment. But then again, who ever said that the fight for freedom isn't a daily battle, never won?
See my other post in this thread. The Obamacare battle is now mostly irrelevant. We now have to fight, equally hard, the battle against Medicare for All. I have no doubt that we would be fighting this new battle regardless of whether Obamacare had passed in the first place, or been overturned.
