The U.S. Supreme Court’s ambiguous institutional position—insulated from external pressures yet retaining important linkages with elected officials—complicates how the public assigns responsibility for its decisions. Using a survey experiment that shows respondents information about Dobbs, we explore how messages that politicize or depoliticize the Court affect responsibility attribution for Court decisions. We find that politicizing the Court increases responsibility attribution towards President Trump, and that this effect is conditioned by party cues. We explore downstream effects on evaluations of political actors, but do not find conclusive evidence. We argue that these findings have important implications for democratic accountability.
