The Constitution of the United States, as originally written, says very little about the role of the vice president. The words “vice president” are actually only used eight times in the entire document.
The Constitution says that the vice president will be the president of the Senate. However, the vice president will not be allowed to vote in the Senate unless there is a tie. Other than that, the only role of the vice president is to step in if the president dies or is removed from office.
Over the years, the vice presidency has become more important, but very little was said about the office in the original Constitution.
