God, I sure hope not.
Yes, and I also think it could happen in 2016. Idaho at least has some parts of the state that are trending Democratic (most notably Boise). WV is probably set to be the next Oklahoma, even though I think that the Eastern Panhandle will trend Democratic over the next 20 years (but not by much and obviously not enough to make the state competitive, so no #VAredux).
Why do you say? (I live in the EP)
Probably Washingtonization
Basically, but more moderate Republicans like Shelley Moore Capito will continue to do very well there.
Worth mentioning that the people who settle in West Virginia rather than Maryland or Virginia are avoiding taxes. The region is pretty well a Republican area. It's going to stay that.
