Answer:
the Framers of the Constitution wanted to ensure that the executive branch was powerful enough to act, and so in Article II of the US Constitution, they established that executive power in the United States is vested in a president, who has certain powers. The powers of the president outlined in Article II are known as formal powers, but over the years presidents have claimed other powers, known as informal powers.
Presidents campaign for office based on their policy agendas: the things they promise voters that they will attempt to accomplish while in office. They use their formal and informal powers to accomplish their policy agendas.
