Judicial Legitimacy, Political Polarization, and How the Public Views the Supreme Court

Abstract

As of late 2020, the makeup of the U.S. Supreme Court consists of six generally conservative Republican appointees and three generally liberal Democratic appointees, one of the first times such a configuration has occurred in decades. In addition, contentious recent confirmation battles may have fundamentally altered public views about the Supreme Court. When it comes to public opinion about the Supreme Court, understanding the institution’s legitimacy and its relationship with political polarization is critical. Institutional legitimacy is a key currency for political bodies—and courts in particular—even as scholarly conceptions of legitimacy differ from popular commentary on the topic. To understand the nature of public opinion toward the Court in a polarized era, one must distinguish between specific support, a type of short-term satisfaction or approval, and diffuse support, commonly known as institutional legitimacy. Recent developments, including controversial confirmation battles and rulings, suggest that partisan and ideological cleavages may increasingly shape the Court’s legitimacy. Scholarship must continue to grapple with Supreme Court legitimacy in a time of political polarization.
