Obama has a very specific problem with white voters

Obama has a very specific problem with white voters — the ones in Appalachia don't like him. The following graph, from DHinMI at Daily Kos, shows the counties where Hillary Clinton won at least 65% of the vote. (The states in white haven't voted yet.)

Interesting pattern, isn't it? However, Obama easily won Utah, Idaho, Wyoming, Colorado, Iowa, Wisconsin, Minnesota, Nebraska, and many other predominantly white states. He's also projected to win white voters in Oregon by 55%–42%. DHinMI concludes:

Obama doesn't appear to have much of a problem with white voters. But it seems quite likely Appalachia has a bit of an Obama problem.
