The 2018 Alaska gubernatorial election took place on November 6, 2018, to elect the governor and lieutenant governor of Alaska. In the primaries for recognized political parties, candidates for governor and lieutenant governor run separately. The winners of each respective primary for governor and lieutenant governor then become a joint ticket in the general election for their political party. Incumbent Independent Governor Bill Walker was seeking re-election in what was originally a three-way race between Walker, Republican former Alaska state senator Mike Dunleavy, and Democratic former Alaska U.S. Senator Mark Begich. Despite Walker dropping out on October 19, 2018, and endorsing Begich, Dunleavy won in what was the only gubernatorial gain by a Republican candidate in 2018. As of 2024, this was the last time the governor's office in Alaska changed partisan control. Walker later unsuccessfully ran for governor of Alaska in 2022.
Democratic–Libertarian–Independence primary.
Candidates from the Alaska Democratic Party, Alaska Libertarian Party and Alaskan Independence Party appear on the same ballot, with the highest-placed candidate from each party receiving that party's nomination. In October 2017 the AKDP sued for the right to allow non-Democrats to compete for and win the Democratic nomination, which was ultimately decided in their favor in April 2018. This move was widely thought to benefit incumbent Gov. Bill Walker, to foreclose the possibility of a Democratic nominee splitting the vote with Walker against a Republican nominee. However, with the entry of former senator Mark Begich into the race, Walker withdrew from the Democratic primary and forged ahead with a fully independent bid for reelection.
