If the Court does declare the act unconstitutional, it would have ruled that Congress lacks the power to adopt what it thought the most effective, efficient, fair, and politically workable remedy—not because that national remedy would violate anyone’s rights, or limit anyone’s liberty in ways a state government could not, or be otherwise unfair, but for the sole reason that in the Court’s opinion our constitution is a strict and arbitrary document that denies our national legislature the power to enact the only politically possible national program. If that opinion were right, we would have to accept that our eighteenth- century constitution is not the enduring marvel of statesmanship we suppose but an anachronistic, crippling burden we cannot escape, a straitjacket that makes it impossible for us to achieve a just national society.

tl;dr: The Affordable Care Act is constitutional as fuck, there’s judicial precedent for keeping it, and four judges are guaranteed to vote against it anyway.
