The United States is undergoing a legal realignment, in that salient legal views recently associated with the right are now being espoused by the left, and vice versa. The clearest example involves Chevron deference: a doctrine once championed by conservatives like Justice Antonin Scalia has now been overruled in Loper Bright v. Raimondo -- over dissenting votes by all three of the Court's liberals. Similar points can be made about standing, stare decisis, textualism, positivism, and more. The basic reason for this transformation is straightforward: legal ideologies in power favor discretion, whereas those out of power favor constraint. Conservatives now firmly control the federal judiciary, so they are gradually abandoning their prior posture of constraint, even as liberals adopt it. As a result, the formalism that characterizes today's legal culture is coming to an end. In the meantime, the left and right's mutual repositioning is helping to preserve both a workable legal system and a degree of shared legal culture.
