I think she may be able to get 40-41%. But if nothing else, I know for a fact she'll at least get one vote.
I really hope she campaigns here though. Like IndyRep said, a majority of voters in this state are Democrats. The problem is they're all Joe Manchin Democrats. They're Democrats who support her on the economy, but oppose her on social issues. Many of them don't turn out to vote. Those that do, usually vote Republican (again, the only exceptions they really make are Joe Manchin and Earl Ray Tomblin, and Robert Byrd when he was around, and so on). If Hillary made a serious attempt to appeal to white blue collar voters, she could flip WV and MO and maybe even AR. But of course, unless the GOP nominates some nut job who has no chance of winning, her resources are going to be better spent in the swing states.
