Presidentialism

Presidentialism is a system of governance where a president serves as the head of state and government, combining executive powers. In this model, the president is elected independently from the legislature, giving them significant authority over administration and policy-making. This structure is characterized by a clear separation of powers among the executive, legislative, and judicial branches, reducing the likelihood of legislative control over the executive. Countries like the United States and Brazil exemplify presidentialism, which can promote strong leadership but may also lead to tensions between branches of government if they are controlled by different political parties.
