Since his wife is a devout Catholic who once worked as an attorney for Feminists for Life, an anti-abortion feminist group, many reasonably questioned his impartiality when it comes to abortion. But they needn't have worried.
The Chief Justice's first loyalty is to the Supreme Court as an institution. Not to the truth, not to what is right, not even to the Constitution. Here he admits that precedent—even a bad one—is more important than any of those things:
Roberts said he thought the court was wrong to strike down the Texas law, but he voted with the majority because that was the binding precedent. "The Louisiana law imposes a burden on access to abortion just as severe as that imposed by the Texas law, for the same reasons. Therefore Louisiana's law cannot stand under our precedents."
Stare decisis is for suckas, and John Roberts is the biggest one of all. Roberts is so concerned with the appearance of the Supreme Court as a trusted, apolitical arbiter of constitutional truth that he'll vote with the four liberal ideologues who make no attempt to hide their blatant disregard for it.
