The Republican nominee for President was Bob Dole, the former Republican Leader of the United States Senate and long-time Senator from Kansas who was previously the vice-presidential running mate of President Gerald Ford in 1976, following Vice President Nelson Rockefeller's retirement from politics that year.  Dole's running mate for Vice President was Jack Kemp, a former NFL football player and the Housing Secretary under George H. W. Bush.  Businessman Ross Perot ran as candidate for the Reform Party with economist Pat Choate as his running mate; he received less media attention and was excluded from the presidential debates and, while still obtaining substantial results for a third-party candidate, by U.S. standards, did not renew his success of the 1992 election.  Turnout was registered at 49.0%, the lowest for a presidential election since 1924.

1840 Democratic National Convention: 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.

William J. Maguire: William J. Maguire (June 12, 1916 – October 2, 1997) was an American Republican Party politician who served in the New Jersey General Assembly from 1976 to 1982.  He served as Mayor of Clark, New Jersey and as a Union County Freeholder.  Maguire was elected to the State Assembly in 1975, running with future Governor Donald DiFrancesco; they defeated incumbent Democrat Betty Wilson and her running mate, William A. Wolf, the Rahway Democratic Municipal Chairman.  He was re-elected in 1977.  Following the resignation of State Senator Peter J. McDonough in 1979, Maguire ran for the State Senate, but lost a vote of a Republican convention to DiFrancesco.  He was re-elected to the Assembly, with future Congressman Bob Franks as his running mate.  Maguire's political career came to an end in 1981, when redistricting traded Democratic towns in Union County for solid Republican towns in Essex County.  DiFrancesco was facing a primary challenge from an Essex County Republican; to secure the Essex organization line in a district where Republican primary election voters were evenly split between Essex and Union, DiFrancesco agreed to put an Essex Republican on his ticket.  John Renna, the Essex Republican Chairman, preferred that Franks (who had worked on Renna's 1977 bid for County Chairman), get the second Assembly seat.  Maguire, replaced by Millburn Mayor Maureen Ogden, did not run for re-election.

Slotback: Slotback (sometimes referred to as an A-back or, especially in the United States, slot receiver) is a position in gridiron football.  The "slot" is the area between the last offensive lineman on either side of the center and the wide receiver on that side.  A player who lines up between those two players and behind the line of scrimmage is a slotback.  The position is a fixture of Canadian football and indoor football, but is also used in American football.  The slotback is similar to the wide receiver but also has many of the same traits as a running back or tight end; a slotback lines up closer to the offensive line and often farther back than a wide receiver.
