This is an odd poll for the Club for Growth to release, considering that Trump defeated Clinton here 68-26. If these swings were replicated nationally, it would point to a fairly decisive Democratic victory.
I don't know what the point of pressuring Manchin not to indict is, since it doesn't matter either way. I guess if Manchin still wants to win an election in WV he should vote against it; I think the conventional wisdom is that he will seek to return to the governorship in 2024.
It's also worth remembering that these are the voters most committed to and invested in him, and if he's losing ground with them, he could be losing even more ground in de-industrialized areas of the rust belt and the rural midwest.
