I'd say the chance that the Democrats keep either Kentucky or West Virginia's State Houses is about as good as Cuomo losing re-election in New York. The Republicans are locks to take both State Houses. If Obama were not incredibly unpopular in both states, then it might be otherwise, but this November will be especially toxic for Democrats in both states (except perhaps in the race against Mitch McConnell).
Democrats chances of taking the Kentucky State Senate: asymptotically approaching zero.
Your certainty is rather impressive given your complete lack of knowledge of Appalachian politics.
