It has been described by some of the people who have held the job as an insignificant one, but it gets attention every four years when presidential candidates are choosing the other half of their ticket. Here's a by-the-numbers look at the vice presidency:
47 -- The number of vice presidents who have served the U.S. since 1789.
13 -- The number of Republican vice presidents since 1900.
10 -- The number of Democratic vice presidents since 1900.
14 -- The number of vice presidents who became president of the United States. Eight of these were because of the death of the sitting president.
4 -- The number of vice presidents who went directly from that office to the presidency. They are John Adams, Thomas Jefferson, Martin Van Buren and George H.W. Bush. Acting as president of the Senate, each man was able to announce his own election to the presidency.
3 -- The number of vice presidents who, as president of the Senate, had to announce they'd lost the presidential election. They are John Breckinridge, Richard Nixon and Al Gore.
