Comparing party registration is a useless exercise. In states with open or semi-closed primaries unaffiliated/independent is always going to be a sizable bloc, and those voters almost always vote with one party or another (i.e. they’re not truly independent swing voters who can be swayed). Just because WV has a huge chunk of independent voters doesn’t mean the partisan lean of voters is anything close to even. West Virginia is an R+22 state, and the battle will be much less about turnout than it is about messaging and recapturing the attention of the working class.
