List of tie-breaking votes cast by vice presidents of the United States The Vice President of the United States is the ex officio President of the Senate, as provided in Article I, Section 3, Clause 4, of the United States Constitution, but may only vote in order to break a tie.[1] According to the U.S. Senate, as of February 28, 2018, a tie-breaking vote had been cast 264 times by 36 vice presidents.[2]
List of Vice Presidents of the United States The United States Constitution assigns few powers or duties to the vice president.[2] The Vice President's primary function is to succeed to the presidency if the President dies, resigns, or is impeached and removed from office. Nine vice presidents have ascended to the presidency in this way: eight (John Tyler, Millard Fillmore, Andrew Johnson, Chester A. Arthur, Theodore Roosevelt, Calvin Coolidge, Harry S. Truman and Lyndon B. Johnson) through the president's death, and one (Gerald Ford) through the president's resignation. In addition, the Vice President serves as the President of the Senate and may choose to cast a tie-breaking vote on decisions made by the Senate. Vice presidents have exercised this latter power to varying extents over the years.[1]
