Why would Clinton worry about what WVa voters have to say about anything? That's very much a Red State. In 2008, McCain won it by 13% and in 2012 Romney won it by 27%. As its 5 Electoral college votes all go to the winner, there's no point bothering about cutting Trump's margin. Clinton merely needed to cut Sanders' margin as the Democratic primaries aren't winner-take-all - pledged delegates are awarded proportionally. Now the primary is over, she couldn't give a damn about WVa.
If you want to figure out how Sanders voters will behave in swing states, you don't analyse exit or other polls in a conservative State. You look at polls in swing states. Even then, why bother doing that before the Democratic nominee has been chosen? Of course, Sanders voters are still hoping for a miracle and will say they'll vote for Trump if they don't get their way. In the highly-likely event that Clinton is the nominee, that emotional blackmail will no longer have any point. Clinton voters in 2008 were vociferous about refusing to vote for Obama if he became the nominee but came back to the fold when she lost. Especially if Sanders wins concessions from Clinton regarding her platform, he'll be happy to campaign for her and call on his supporters to vote for her and against Trump. Senator Elizabeth Warren has a good chance of becoming Clinton's running mate and she's Bernie Sanders in drag.
