Midterm elections have forced presidents to adjust course, reshaped their relationship with the party they lead, and heralded the rise or fall of new electoral coalitions. This book presents a fresh perspective on the American presidency by analysing how midterms modify in crucial ways the mandate that a president gained at the time of their election to the White House. Midterms not only provide an important opportunity for voters to evaluate the record of a president so far, but also have consequences for an administration's pursuit of the president's agenda over the two years that follow. Bringing together political scientists and historians, this collection presents a multidisciplinary understanding of the interplay between midterm elections and the American presidency.Patrick Andelic is Senior Lecturer in American History at Northumbria University.
