-
Montana:
Obama 57
Clinton 41

South Dakota:
Clinton 55
Obama 45

-
This, of course, was the end. With all 50 states, plus 4 more contests (Guam, Puerto Rico, D.C., and Democrats Abroad), having voted, Obama claimed victory and Clinton, after a final rally to buck up her bewildered supporters, quickly conceded the nomination. South Dakota was, ironically, Hillary's only win in the Mountain West states.
