A political system that empowers the leader with the ultimate responsibility to execute laws is called presidentialism. In a presidential system, the head of state (usually referred to as the president) serves as both the head of government and the commander-in-chief of the armed forces. The president is elected by the people, and they are directly accountable to the citizens of the country for their actions. The president has a significant amount of power and is responsible for making executive decisions, enforcing laws, and carrying out government policies. The presidential system is commonly found in countries like the United States, Brazil, and Mexico.
