Severability 6-3 Favor(Left+Kavanaugh, Gorsuch, and Roberts)
Gorsuch straight-up doesn't believe in severability regardless of the legislation in question, and I don't trust ACB as far as I can throw her not to be a lockstep right-wing ideologue. If the Court finds for severability it'll be 5-4 with only Roberts and Kavanaugh joining the liberals.
Whatever the final policy outcome, I'm expecting a messy decision with lots of concurrences in part, dissents in part, possibly a per curiam plurality opinion rather than a real majority decision, etc. The works.
