This book analyzes the legacy of the first Trump administration on a variety of different fronts. Whether it was the extensive use of Twitter, the tendency to express controversial, and often dubious views, or to even slander foreign leaders, Trump was a disruptive president. The presidency of Donald Trump raises questions for political scientists and researchers. How consequential was he? While he garnered much attention both in and out of the White House, how much of his legacy remains? The authors in this book address these questions with essays that cover an array of issues related to his tenure in office, and the years since. The chapters provide a broad analysis of the legacy of the Trump presidency, focusing on all aspects of his presidency and representing multiple perspectives across the partisan and disciplinary divides. Additionally, the contributions in this book aim to (re-)assess the Trump legacy in light of the subsequent efforts by his successor to undo much of the policies embraced by and implemented during the Trump years.
