The State of Alaska is one of the most generous (if not the most generous) hand-out states in the nation, which attracts entitlement types. Those who depend on entitlements vote democratic so as to continue their entitlements. Then they have children (lots of children) who are born into the same culture and vote the same way...

 Therefore I think, unfortunately, that you may be right -- may be heading for blue-dom eventually. I think it will take a lot longer then you think though; Alaska will continue to attract conservative leaning groups such as oil, mining, military, fishing, hunting, and so on... but eventually they will be outnumbered.
