Predicting a Second Trump Term: The Challenges for Political Science

Studying and forecasting the policy behavior of a potential second-term Donald Trump, often referred to as “Trump 2.0,” presents a meaningful theoretical challenge for political scientists. If the 2017-2020 term weakened the traditional predictive power of US presidential models, a 2025-2029 term indicates an even greater degree of structural uncertainty. This stems not only from the personalization of Trump’s power but also from the change of the internal political environment and the volatility of the international system. Recognizing thes factors reveals the problem isn’t solely Trump’s unpredictable personality, but that the US political system under a “Trump-style” president has become difficult to predict using conventional methods.

Classical works on the US presidential model typically describe the institutional ecosystem as operating with interagency consultation.Implementation agencies, like the Department of Defense or the Department of State, stabilize the policy process, and the president adjusts behavior to meet the expectations of their political party, Congress, and public opinion. Trump, especially in the current context, doesn’t fit this model. The increasing personalization of power, the elimination of decision-making constraints (like a traditional national security team), and a focus on absolute loyalty render predictive models based on “executive practice” analytically invalid.

This is compounded by a changing legal environment. A president facing civil or criminal lawsuits finds political action influenced by the logic of defense, voter mobilization, and controlling public opinion, rather than purely strategic criteria. This configuration means policy behavior isn’t consistent with a common strategic trajectory, but instead shifts according to the rhythm of legal judgments.

A key factor increasing uncertainty in forecasting “Trump 2.0” is the restructuring of the personnel apparatus.Contrary to popular belief, Trump’s first term still relied on figures from the security world with pragmatic views, such as James Mattis, HR McMaster, John Kelly, and Rex Tillerson. These individuals, with their political

Key Takeaways

• Traditional US presidential models struggle to predict the behavior of a president like Donald trump due to his personalized power and disregard for established norms.
• The legal challenges facing a president can substantially influence policy decisions, shifting focus from strategic goals to legal defense and public opinion control.
• A shift in personnel, away from pragmatic advisors, further increases the unpredictability of a second Trump term.

forecasting a second Trump term requires acknowledging the fundamental shifts in the US political landscape. Conventional methods are insufficient. the interplay of legal battles, a personalized power structure, and a potentially more ideologically aligned personnel apparatus creates a uniquely unpredictable environment. Looking ahead, political scientists must develop new analytical frameworks that account for these factors, focusing less on traditional institutional constraints and more on the individual motivations and external pressures shaping presidential decision-making. Further research should explore the impact of social media and direct dialog with supporters on policy formulation and implementation, as these channels appear to bypass traditional gatekeepers and amplify the president’s personal influence.
