Have perceptions of the U.S. Supreme Court polarized, much like the rest of American politics? Because of the Court’s unique role, for many years, it remained one of the few institutions respected by both Democrats and Republicans alike. But the Court’s dramatic shift to the right in recent years—highlighted by its Dobbs decision in 2022—potentially upends that logic. Using both eight waves of panel data and 18 nationally representative surveys spanning two decades, we show that while there was little evidence of partisan polarization in earlier years, in 2022 and 2023, such patterns are clear in favorability, trust, legitimacy, and support for reform. Factors that used to protect the Court—like knowledge about it and support for key democratic values—no longer do so. The Court has also become more important to voters, and will likely remain a political flashpoint, with disquieting implications for the Court’s place in our polity.
