But, until then, Gov. Sarah Palin appoints his successor.
it's complicated. alaska actually has two laws on the books regarding senate vanancies; one was a ballot measure that passed, and one was a bill passed by the alaska state legislature. both were enacted in 2004. the alaska supreme court will have to decide which one prevails.
they both call for a special election, but only one allows sarah palin to appoint an interim successor. but I believe that both remedies require a special election within 90 days.
