I have never been to the state and I know no one from there. But everything I can find on Wikipedia and Google gives me no indication of what that anomaly was about. All their other modern era election results seem to be fairly right leaning or centrist. Yet in his first election he managed to win despite a solid third-party effort from a fellow Democrat. Then he got reelected after filibustering a draft extension, and seeming culturally out of touch with the state, not being a hunter or fisherman.
I see that Alaska does have a larger Green Party presence than many states; but it still seems like the Republicans are more powerful than Greens and Democrats combined. So what gives?
