The major difference between these two systems is that in a Presidential system, the executive leader, the President, is directly voted upon by the people (Or via a body elected specifically for the purpose of electing the president, and no other purpose), and the executive leader of the Parliamentary system, the Prime Minister, is elected from the legislative branch directly. The President only responds to the people, the legislative branch can't really do anything to threaten the President. As a result, he can make it more difficult for the legislative body to do anything. If the Parliament doesn't like the Prime Minister, they can cast a vote of no confidence and replace him. This tends to make the executive leader subservient to the Parliament. "Our government under the proposed [Constitution], will be guarded by a repetition of the strongest cautions against excesses [abuse of power]. In the senate the sovereignties [powers] of the several states will be equally represented; in the house of representatives, the people of the whole union [all the states] will be equally represented; and, in the president, and the federal independent judges, so much concerned in the execution [carrying out] of the laws, and in the determination of their constitutionality, the sovereignties of the several states and the people of the whole union, may be considered as . . . represented."
—John Dickinson, The Letters of Fabius, in 1788, on the Federal Constitution
