Birds on the Brain

I doubt there was a single reason for the chief justice’s evolution (I know, conservatives hate that word in the context of Supreme Court justices’ ideological trajectories), but let me suggest one: the breathtaking radicalism of the other four conservative justices. The opinion pointedly signed individually by Justices Kennedy, Thomas, Antonin Scalia and Samuel A. Alito Jr. would have invalidated the entire Affordable Care Act, finding no one part of it severable from the rest. This astonishing act of judicial activism has received insufficient attention, because it ultimately didn’t happen, but it surely got the chief justice’s attention as a warning that his ostensible allies were about to drive the Supreme Court over the cliff and into the abyss.
