Presidential Influence Over the Systemic Agenda

One of the most widely accepted sources of presidential power is agenda setting. Being able to affect the media's agenda on key issues–influencing the systemic agenda and expanding the scope of conflict–has enormous consequences for the president's ability to govern effectively. Yet the literature to date has not conclusively determined the extent to which presidents consistently set agendas, especially over the media, because it has not explicitly considered variation in agenda setting influence by policy type. For these reasons, we test whether presidential public statements have increased the media's attention to three policy areas. Using Vector Autoregression (VAR) analysis, we demonstrate that presidents have some influence over the systemic agenda, at least in the short term, with policy type being an important predictor of presidential influence. Understanding when and why presidents may or may not be successful agenda setters is crucial to explaining the varying legislative impacts of presidential speech making.
