I haven’t heard anything about a possible need for a runoff, so maybe Alaska law doesn’t require it. It varies from one state to another, and I believe that in most states the winning candidate is the one with the most votes, not necessarily requiring a candidate to have a majority of the votes. This was how Jesse Ventura was elected governor of Minnesota a while back even though he only got something like 36% of the popular vote.
Okay, I read somewhere that if they didn’t get 40% there would be one.
Or maybe only if Miller won. /s
