Whatever merit progressive proposals to contract the power and prestige of the Supreme Court might have, they are not a plausible means of restoring it to its former role as the champion of liberal principles. A court with reduced jurisdiction, whose members fear removal by the political branches and whose decisions command little respect from the broader political culture: That's not an institution that can perform what Jackson recently called "the singular function of ensuring compliance with the Constitution" and "protecting people's rights."

A high regard for the court is particularly important now that progressives have (rightly) made it a priority to make Trump follow court orders. They can argue that the court is illegitimate or that Trump has a high duty to obey it. They seem unlikely to persuade the public that Trump has a solemn obligation to comply with an illegitimate court.
