Montana gubernatorial election, 1936: The 1936 Montana gubernatorial election took place on November 3, 1936.  Incumbent Governor of Montana Elmer Holt, who became governor in 1935 upon the death of Frank Henry Cooney, ran for re-election.  He was challenged in the Democratic primary by a number of challengers, and was narrowly defeated for renomination by United States Congressman Roy E. Ayers of Montana's 2nd congressional district.  Ayers advanced to the general election, where he faced Frank A. Hazelbaker, the former Lieutenant Governor of Montana and the Republican nominee.  Following a close election, Ayers narrowly defeated Hazelbaker to win what would be his first and only term as governor.

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.

After winning the Republican primary against a conservative activist, he moved on to the general election, where he was set to face Chet Blaylock, a former State Senator and the Democratic nominee.  However, on October 23, 1996, Blaylock died of a heart attack, and the Montana Democratic Party selected his running mate, State Senator Judy Jacobson, to replace him as the gubernatorial nominee, and she therefore appeared on the ballot as both the gubernatorial nominee and the lieutenant gubernatorial nominee.  Ultimately, however, Racicot was able to defeat Jacobson in a landslide to win re-election to his second and final term as governor.

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.

Stan Stephens, the former President of the Montana Senate, won a close Republican primary, and advanced to the general election, where he was opposed by Thomas Lee Judge, Schwinden's predecessor as governor and the Democratic nominee.  Though the general election was hotly contested, Stephens ultimately defeated Judge, becoming the first Republican to win a gubernatorial election in Montana since 1964.
