Alaska is moving toward the Democrats. It's a ways away from being a swing state, but enough liberal environmental types have moved in to re-elect Begich.
Do you know that for a fact, and if so, do you have a source? I'd be curious to know how the voting demographics of Alaska are changing.
It's hard to believe Alaska would see a wave of people migrating to live there. It's days in the safe GOP column may be numbered though.
For whatever reason Alaska is shifting D, fast. This isn't just due to Palin- it's been trending D since 1992, and it's really begun to accelerate. It went from R+30 in 2000 to R+16 now. At this rate it will be Democratic by 2028. It could easily be the next Vermont.
