"Above and beyond their partisan attitudes, Americans have specific beliefs about the nature of presidential power," said Andrew Reeves, political scientist and Weidenbaum Center Fellow at Washington University in St. Louis and co-author of a new research paper, in an interview. "They're naturally hesitant on the nature of these unilateral actions." Reeves and Jon Rogowski, another political scientist at Washington University, published their work in December 2015. They found that the public has views on executive authority distinct from who is using it. The academics tried to isolate whether the way in which a president wants to enact a policy has an impact on that policy's popularity.
