I agree. It does seem like there are a couple of states on each side that flirt with getting rid of a D or R, but the state seems to revert back to their "comfort" zone in the end.
However, historically, we know that eventually ends. Think of Texas, where (D) was the thing to be not that long ago. But, yeah, I cannot envision Stevens losing, but I will be sending Begich money if I think it is possible!
