The term is often associated with the Boeing C-32, a modified 757 which is most commonly used as the Vice President's transport.

Joseph Robinette "Joe" Biden Jr. ( ; born November 20, 1942) is an American politician who was the 47th Vice President of the United States from 2009 to 2017.  A member of the Democratic Party, he represented Delaware as a United States Senator from 1973 until becoming Vice President in 2009. The 1840 Democratic National Convention was held in Baltimore.  The Democrats nominated President Martin Van Buren for reelection in 1840 in spite of his unpopularity following the Panic of 1837.  Vice President Richard M. Johnson was not retained on the ticket, as he was largely seen as a liability in the 1836 election and had focused much of his time as vice president on his own economic affairs.  Former President Andrew Jackson backed James K. Polk for the position of vice president, but Van Buren supported his vice president's renomination.  The convention ultimately decided not to nominate a running mate for Van Buren.  As a result, Van Buren became the only major party presidential nominee since the passage of the 12th Amendment to seek election without a running mate. Glen F.
