Nope, I know all about the history of democratic senators in WV. I was referring to the last 10 years or so and the foreseeable future.
Notice a trend in the numbers you posted? Manchin went from +24 to +3 in 6 years. If you don't see where this is going and think Manchin has a good shot at reelection, I have a lightly used bridge over the San Fransisco Bay to sell you. If he gets primaried by a more liberal candidate, it will be a blood bath.

Keep fucking that chicken, but I have some bad news for you, West Virginia is as likely to swing back to Democrats as is Jaylon Waddle transferring to Texas. A change in Dem messaging is not going to overcome the fact that it's the 3rd most rural population state in the country along with being last in education (using a number of metrics), etc.. etc.... They already receive the 9th highest amount of federal spending per capita.
Maybe when were not in 50-50 Senate and moderates are not going to want to use a nuclear option?
