UPDATE: An unusual, and well executed, preemptive concession from Obama:
There is an election here tomorrow. I’m honored that some of you will support me, and I understand that many more here in West Virginia will probably support Senator Clinton. But when it’s over, what will unify as Democrats – what must unify us as Americans – is an unyielding commitment to the men and women who’ve served this nation and an unshakable fidelity to the ideals for which they’ve risked their lives.
