This concluding chapter begins with a summary of findings by revisiting the questions we posed in the first chapter. What influences the president’s immigration policy agenda and tone, and does the president’s agenda motivate the news and public immigration policy agendas? If presidents have adopted a public relations strategy to achieve immigration policy reform in Congress, why have presidents been unsuccessful? The big picture is that presidents have failed to lead on a salient policy like immigration but instead follow the public, news, and legislative agendas. Examining the reciprocal and causal relationships between presidential, public, news media, and legislative agendas confirms our earlier results as to why Congress and the president have failed to revise immigration policy since the 1990s. The penultimate section explores whether the Biden administration presents an opportunity for renewed presidential leadership on immigration. The chapter closes with avenues for future research.
