August 31 was the deadline for Alaska candidates who were in the top four in the primary, to withdraw from the general election. When that happens in Alaska, other candidates who weren’t originally in the top four replace them. Lots of candidates for the three statewide offices withdrew. See this story. One result was that Libertarian Jim McDermott, running for U.S. House, is now on the November ballot for U.S. House. See this story.
Also, see this story, which has interesting details about the gubernatorial race.
It is plausible that in November, Alaska voters will elect an independent to be Lieutenant Governor. Zac Johnson is the running mate of the Democratic gubernatorial slate headed by Jonathan Kreiss-Tomkins. Kreiss-Tomkins chose an independent running mate to emphasize his outreach to independent voters.
It is also plausible that in November, Alaska will elect an independent to the U.S. House. He is Bill Hill, and Democrats are supporting him. There is a Democrat running for U.S. House but he is in a federal prison in South Dakota and thus has no active campaign.
