what is presidential form of government

A presidential form of government is a system in which a head of government, typically with the title of president, leads an executive branch that is separate from the legislative branch. This system is characterized by the separation of powers, where the president is elected to work alongside, but not as a part of, the legislature. The president is usually also the head of state. The presidential system is prevalent in the mainland Americas, Central and southern West Africa, and Central Asia, with the United States being the originator and primary example of this system. In this form of government, the president has extensive powers related to both domestic and foreign policy, and is independent from the legislature, being directly accountable to the people. The system also includes checks and balances among the three separate branches of government to prevent any one branch from dominating continuously. The presidential system is designed for a federation, with independent state governments that cannot be dissolved and are required to be self-sufficient. This system grants limited powers, empowers state governments, separates the three branches into different institutions, and gives the people a direct say through direct elections at all levels of government.
