Sorry, I shouldn't have tried to "show off" my knowledge of the Constitution as a non-citizen of the U.S. I should have been perfectly clear, so: This info comes from: www.usa.gov/branches-of-government so if you're still in doubt try haranging them. How the U.S. Government Is Organized The Constitution of the United States divides the federal government into three branches to ensure a central government in which no individual or group gains too much control: Legislative – Makes laws (Congress) Executive – Carries out laws (President, Vice President, Cabinet) Judicial – Evaluates laws (Supreme Court and Other Courts) Each branch of government can change acts of the other branches as follows: The president can veto laws passed by Congress. Congress confirms or rejects the president's appointments and can remove the president from office in exceptional circumstances. The justices of the Supreme Court, who can overturn unconstitutional laws, are appointed by the president and confirmed by the Senate. The U.S. federal government seeks to act in the best interests of its citizens through this system of checks and balances. You can take solace in knowing you are not alone in being confused on this issue. There are Constitutional arguments that have gone on for years. For all of it's beauty and importance in the History of Democracy it is not exactly a model of clarity to the modern eye. Wiki says: The United States Constitution does not expressly assign the office to any one branch, causing a dispute among scholars whether it belongs to the executive branch, the legislative branch, or both. The modern view of the vice president as a member of the executive branch is due in part to the assignment of executive duties to the vice president by either the president or Congress, though such activities are only recent historical developments. Here is some info on what may add to or clarify the confusion, including the amendments I mentioned at one point: Clause 3: Electors "...A quorum for this Purpose shall consist of a Member or Members from two thirds of the States, and a Majority of all the States shall be necessary to a Choice. In every Case, after the Choice of the President, the Person having the greatest Number of Votes of the Electors shall be the Vice President. But if there should remain two or more who have equal Votes, the Senate shall chuse [sic] from them by Ballot the Vice President". The Twelfth Amendment introduced a number of important changes to the procedure. Now, Electors do not cast two votes for President; rather, they cast one vote for President and another for Vice President. In case no Presidential candidate receives a majority, the House chooses from the top three (not five, as with Vice Presidential candidates). The Amendment also requires the Senate to choose the Vice President from those with the two highest figures if no Vice Presidential candidate receives a majority of electoral votes (rather than only if there's a tie for second for President). It also stipulates that to be the Vice President, a person must be qualified to be the President. By the time of their inauguration, the President and Vice President must be: natural born citizens, at least 35 years old, inhabitants of the United States for at least fourteen years. Eligibility for holding the office of President and Vice-President were modified by subsequent amendments: The Twelfth Amendment (1804) requires the Vice-President to meet all of the qualifications of being President. The Twenty-second Amendment (1951) prevents a President from being elected more than twice Clause 6: Vacancy and disability In Case of the Removal of the President from Office, or of his Death, Resignation, or Inability to discharge the Powers and Duties of the said Office, the Same shall devolve on the Vice President, and the Congress may by Law provide for the Case of Removal, Death, Resignation or Inability, both of the President and Vice President, declaring what Officer shall then act as President, and such Officer shall act accordingly, until the Disability be removed, or a President shall be elected. (Note: This clause was partially superseded by the Twenty-fifth Amendment in 1967.) The Twenty-fifth Amendment explicitly states that when the Presidency becomes vacant, the Vice President becomes President, and also establishes a procedure for filling a vacancy in the office of the Vice President. It supersedes the ambiguous wording of this clause. The Amendment further provides that the President, or the Vice President and Cabinet, can declare the President unable to discharge his duties, in which case the Vice President becomes Acting President. If the declaration is done by the Vice President and Cabinet, the Amendment permits the President to take control back, unless the Vice President and Cabinet challenge the President and two-thirds of both Houses vote to sustain the findings of the Vice President and Cabinet. If the declaration is done by the President, he may take control back without risk of being overridden by the Congress.
