The chapter presents a summary of main findings and discusses their implications. The book’s main finding is that extreme power asymmetry on behalf of the Incumbent creates the conditions for institutional change that empowers mostly the executive branch. A large power differential between the Incumbent and the Opposition encourages the Incumbent to seize the advantage to initiate bold, self-serving institutional change, sometimes even a constitutional overhaul. If the latter gets underway, and power asymmetry stays pro-Incumbent, chances are the new constitution will expand the powers of the Executive branch. This outcome, in turn, can spread discontent across Opposition forces and sometimes encourage the Incumbent to govern more unilaterally. This presents a potential threat to democracy. The chapter concludes by discussing the implications of this finding for different literatures: democratization, constitution-making, presidential powers, and government-Opposition relations.
