Barack Obama needs 47 more delegates to claim the Democratic nomination outright, according to the Associated Press. The party's last two primaries will be held tomorrow in Montana and South Dakota. Those states offer 31 delegates combined and Obama is expected to take both states.
If/when that happens Obama will need to persuade only a handful of the party's remaining unpledged 201.5 "superdelegates" to become the Democratic nominee.
On the flip side, and not counting any delegates she may win in Montana or South Dakota tomorrow, Clinton is currently 202.5 delegates shy of the nomination.
