Has Trump Trumped the Courts?

President Trump’s repeated and unsparing criticisms of the federal judiciary provide an opportunity to examine how public critique of the U.S. Supreme Court affects Americans’ willingness to support the institution. We report the results of an experiment embedded in a nationally-representative survey of Americans that varied in both the source (President Trump or distinguished law professors) and content (legal or political) of the criticism aimed at the Court. Our results—perhaps surprising to many—demonstrate that the greatest decline in support for the Court came among those respondents who learned of criticism by law professors that the Court’s decisions are politicized. The results have important implications for our understanding of the Court’s legitimacy under President Trump.
