As you can see on the map I linked to, the Appalachian belt has consistently been giving Clinton >65% wins throughout the primaries. WV is the only state that is 100% within that belt, hence WV was almost certainly going to be a >65% Clinton win. After WV, KY has the largest percentage of its population within that belt, so it is the other state likely to give Clinton a >65% win, though that depends on how Louisville balances it out (I predict Obama will win Louisville itself, though Clinton will probably win its suburbs, and I don't know how its turnout will compare with the eastern part of the state).
