It's also the margins in those counties. 45%+ in many of the VA counties that border WV (and when Trump was polling close to 10% lower nationally), 50%+ in much of eastern KY (despite that being a caucus state, where Trump has generally done poorly), 45-50%+ in the bordering OH counties
against that state's sitting governor, over 60% in the bordering counties of southwest PA, and 55%+ in the three counties in the panhandle of MD. I can't imagine Trump getting less than 55% in WV at this point, and something like 60-65% seems more likely.
