Context paragraphs:
Oregon gubernatorial election, 2006: The 2006 Oregon gubernatorial election took place on November 7, 2006.  Incumbent Democratic Governor of Oregon Ted Kulongoski ran for a second and final term as governor.  Kulongoski faced several challengers in his primary, whom he dispatched to win his party's nomination a second time, while Republican nominee Ron Saxton, the former Chair of the Portland Public Schools Board and a candidate for governor in 2002 emerged from a crowded primary.  Kulongoski and Saxton were initially going to be challenged in the general election by State Senator Ben Westlund, but Westlund withdrew his candidacy before the general election.  There were, however, a number of strong independent challengers, the most notable of whom was Mary Starrett, the Constitution Party nominee.  In a hard-fought campaign, Kulongoski won re-election by a surprisingly wide margin, winning his second term as governor.

Vermont gubernatorial election, 2010: The 2010 Vermont gubernatorial general election took place on November 2, 2010.

Incumbent Governor of Montana Marc Racicot, who was first elected in 1992 and was re-elected in 1996, was unable to seek re-election due to term limits.  Judy Martz, the Lieutenant Governor of Montana under Racicot for four years, won the Republican primary and advanced to the general election, where she faced Mark O'Keefe, the Montana State Auditor and Democratic nominee.  Despite the fact that George W. Bush, the Republican nominee for president in 2000, won the state in a landslide, the race between Martz and O'Keefe was close.  However, Martz managed to narrowly defeat him to win her first and only term as governor.  As of 2017, this is the most recent election in which a Republican was elected Governor of Montana.

Erickson, a former district court judge and the Democratic nominee; and Frank J. Edwards, the 1916 Republican nominee for governor and the Farmer–Labor Party nominee.  Ultimately, Erickson managed to defeat Dixon in his bid for re-election, winning what would be the first of three terms as governor.

Alaska gubernatorial election, 1982: The 1982 Alaska gubernatorial election took place on November 2, 1982 for the post of governor of Alaska.

Montana gubernatorial election, 1996: The 1996 Montana gubernatorial election took place on November 5, 1996.  Incumbent Governor of Montana Marc Racicot, who was first elected in 1992, ran 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.

Montana gubernatorial election, 1992: The 1992 Montana gubernatorial election took place on November 3, 1992.

Marc Racicot, the Attorney General of Montana, won the Republican primary and advanced to the general election, where he faced State Representative Dorothy Bradley, who had emerged from a crowded Democratic primary as the nominee of her party.  A close election ensued, but in the end, Racicot ended up defeating Bradley to win his first of two terms as governor.
