Alaska As Swing State?

Silver thinks it's possible:

If the Democratic nominee in 2016 is someone like Hillary Rodham Clinton, who embraces a relatively traditional Democratic agenda, she will have better places to compete. But a Democrat who was perceived as being of the center-left or the libertarian left, especially one from a western state like Colorado’s governor, John W. Hickenlooper, could conceivably be competitive in Alaska. And if Alaska continues to add population from states like California and Washington, it could be competitive on a more regular basis in 2020 and going forward.
