Question: When was Thomas Eagleton's running mate born?
Context: The United States presidential election of 1996 was the 53rd quadrennial presidential election.  It was held on Tuesday, November 5, 1996.  The Democratic national ticket was led by incumbent President Bill Clinton, and his running mate, incumbent Vice President Al Gore.  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. The United States presidential election of 1972, the 47th quadrennial presidential election was held on Tuesday, November 7, 1972.  The Democratic Party’s nomination was eventually won by Senator George McGovern of South Dakota, who ran an anti-war campaign against Republican incumbent President Richard Nixon, but was handicapped by his outsider status, limited support from his own party, the perception of many voters that he was a left-wing extremist and the scandal that resulted from the withdrawal of vice-presidential nominee Thomas Eagleton. Robert Skinner Boyd (born January 11, 1928) is an American journalist who spent most of his career working for the Knight Newspaper Group, spending two decades as the group's Washington bureau chief.  He and Clark Hoyt won a Pulitzer Prize in 1973 for uncovering the fact that Senator Thomas Eagleton, George McGovern's choice for vice president, had had severe psychiatric problems and undergone three shock treatments.  Instead of publishing their scoop, they disclosed their findings to McGovern's top advisor, and Eagleton withdrew as the Democratic nominee. The 2016 United States presidential election in Utah was held on November 8, 2016, as part of the 2016 General Election in which all 50 states plus The District of Columbia participated.  Utah voters chose electors to represent them in the Electoral College via a popular vote pitting the Republican Party's nominee, businessman Donald Trump, and running mate Indiana Governor Mike Pence against Democratic Party nominee, former Secretary of State Hillary Clinton and her running mate, Virginia Senator Tim Kaine. George Stanley McGovern (July 19, 1922 – October 21, 2012) was an American historian, author, U.S. Representative, U.S. Senator, and the Democratic Party presidential nominee in the 1972 presidential election. The 2016 United States presidential election in Ohio was held on November 8, 2016, as part of the 2016 General Election in which all 50 states plus The District of Columbia participated.  Ohio voters chose electors to represent them in the Electoral College via a popular vote pitting the Republican Party's nominee, businessman Donald Trump, and running mate Indiana Governor Mike Pence against Democratic Party nominee, former Secretary of State Hillary Clinton and her running mate, Virginia Senator Tim Kaine. The 2008 presidential campaign of John McCain, the longtime senior U.S. Senator from Arizona, was launched with an informal announcement on February 28, 2007 during a live taping of the "Late Show with David Letterman", and formally launched at an event on April 25, 2007.  His second candidacy for the Presidency of the United States, he had previously run for his party's nomination in the 2000 primaries and was considered as a potential running mate for his party's nominee, then-Governor George W. Bush of Texas.  After winning a majority of delegates in the Republican primaries of 2008, on August 29, leading up to the convention, McCain selected Governor Sarah Palin of Alaska as his running mate for Vice President.  Five days later, at the 2008 Republican National Convention, McCain was formally selected as the Republican Party presidential nominee in the 2008 presidential election. The 1992 vice-presidential debate was part of the 1992 presidential election.  The participants were Democratic nominee, Bill Clinton's running mate, U.S. Senator Al Gore from Tennessee; Ross Perot's running mate, retired Vice Admiral James Stockdale; and Republican candidate, incumbent Vice President Dan Quayle.  It was held on Tuesday, October 13, 1992. 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. Arthur Sewall (November 25, 1835 – September 5, 1900) was a U.S. Democratic politician from Maine most notable as William Jennings Bryan's first running mate in 1896.  As the Populist Party nominee, Bryan had another running mate as well, Thomas E. Watson.  Sewall never held elective office, although he was a member of the Democratic National Committee from 1888 to 1896.
