Dr. Sharon Chamard, Justice Center faculty and Director of the Survey Research Center, was interviewed by Josh Katz of The New York Times for the NYT blog, "The Upshot", about difficulties in conducting polls in Alaska.
The blog post mentions low response rates (which are a problem everywhere), and Alaska's small population which compounds the problems of low response rates. Dr. Chamard commented that in addition to these issues, residential transiency - people moving in and out of state - makes it a challenge to compile a sample of sufficient size to yield reliable data.
