Understanding Semi-Presidentialism and the Dynamics of Cohabitation
Semi-presidentialism is a hybrid system: a directly elected president shares executive power with a prime minister who commands a majority in parliament. When the president's party loses the parliamentary election, the president must appoint a prime minister from the opposition—this is cohabitation. In such periods, the president retains powers like foreign affairs and defense, while the prime minister controls domestic policy and legislation. The shift is dramatic: from a president-led executive to a parliamentary-style government, where the prime minister becomes the dominant actor in day-to-day governance.
A deeper explanation
Cohabitation emerges from the dual sources of legitimacy: the president and the parliament are elected separately, so they can represent different political forces. The prime minister, accountable to parliament, needs its confidence to govern; the president cannot dismiss a prime minister who has parliamentary support. This forces a division of labor, often called 'dual executive' power. The president focuses on diplomacy and national security, while the prime minister manages the economy and domestic affairs. This arrangement tests the flexibility of the constitution and shapes policy outcomes, as neither branch can dominate fully, requiring negotiation and compromise.
