Who was the principle advocate of a weak executive at the Founding?

The principal advocate of a weak executive during the Founding was Thomas Jefferson. He believed in a limited government with a strong emphasis on states' rights and feared that a powerful executive could lead to tyranny. Jefferson's views were in contrast to those of Alexander Hamilton, who supported a stronger national government and executive authority. This debate over the balance of power between the executive and other branches of government was a significant aspect of the early American political landscape.
