Question: Jack Ciattarelli lost the primary election in 2017 to the running mate of which governor?
Context: The 2008 Montana gubernatorial election was held on November 4, 2008 to elect the governor and lieutenant governor of the U.S. state of Montana.  Incumbent governor Brian Schweitzer, a Democrat who was elected to his first four-year term in 2004, was elected to a second term with 65.5 per cent of the vote.  John Bohlinger, a Republican and the incumbent lieutenant governor, was once again Schweitzer's running mate, and was re-elected to a second term.  The Republican nominee was Roy Brown, a member of the Montana Senate.  Brown's running mate was businessman, and future U.S. Representative and U.S. Senator, Steve Daines. 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 Kentucky gubernatorial election, 2007 was held on November 6, 2007.  In this election, incumbent Republican Governor Ernie Fletcher lost to Democratic challenger Steve Beshear, who therefore began serving as Governor of Kentucky in December 2007 for a term through December 2011.  A primary election to determine the Republican and Democratic nominees for governor was held on May 22, 2007 in which Ernie Fletcher (Republican) and Steve Beshear (Democrat) won their respective primaries.  Beshear's running mate, Daniel Mongiardo, was elected as Lieutenant Governor of Kentucky for that same time period. Jack M. Ciattarelli (born December 12, 1961) is an American entrepreneur and politician who has served in the New Jersey General Assembly since December 2011, representing the 16th legislative district.  He is a member of the Republican Party, and ran for Governor of New Jersey in the 2017 election, losing the primary election to Kim Guadagno, the Lieutenant Governor of New Jersey. The 2012 United States presidential election in Utah took place on November 6, 2012 as part of the 2012 General Election in which all 50 states plus The District of Columbia participated.  Utah voters chose six electors to represent them in the Electoral College via a popular vote pitting incumbent Democratic President Barack Obama and his running mate, Vice President Joe Biden, against Republican challenger and former Massachusetts Governor Mitt Romney and his running mate, Congressman Paul Ryan.  Prior to the election, all 17 news organizations considered this a state Romney would win, or otherwise considered as a safe red state.  Utah is among the most heavily Republican states, voting for the Republican ticket in every presidential election since 1968, and is also the only state to have a majority Mormon population, benefiting Romney, the first Mormon to head a major party presidential ticket.  He carried every county in the state, all by large margins.  However, Obama would go on to win reelection nationwide. Glen J. Smith (born) is a United States Virgin Islander educator and teacher.  Smith was chosen by gubernatorial candidate Gerard Luz James as his running mate for Lieutenant Governor of the United States Virgin Islands in the 2010 gubernatorial election.  James and Semith ran as Democrats, but lost the Democratic primary election. The 2012 United States presidential election in Ohio took place on November 6, 2012 as part of the 2012 General Election in which all 50 states plus The District of Columbia participated.  Ohio voters chose 18 electors to represent them in the Electoral College via a popular vote pitting incumbent Democratic President Barack Obama and his running mate, Vice President Joe Biden, against Republican challenger and former Massachusetts Governor Mitt Romney and his running mate, Congressman Paul Ryan.  This continued the streak of having the winner of the overall election winning Ohio as the state has not voted for a losing candidate since Richard Nixon in 1960. In 2006, Sarah Palin was elected governor of Alaska.  Running on a clean-government platform, Palin defeated incumbent Governor Frank Murkowski in the Republican gubernatorial primary election in August.  She then went on to win the general election in November, defeating former Governor Tony Knowles 48.3% to 40.9%.  Her running mate was State Senator Sean Parnell. Kimberly Ann "Kim" Guadagno (pronounced "gwah-DAHN-oh"; born April 13, 1959) is an American politician, attorney, former Sheriff, and the first Lieutenant Governor of New Jersey, having won the 2009 and 2013 elections as the running mate of Governor Chris Christie.  She is concurrently the Secretary of State of New Jersey.  Guadagno is the Republican party nominee in the 2017 gubernatorial election. 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.
Answer: Chris Christie
