Hillary Clinton picked up one delegate yesterday.
Obama picked up four.
(You'll note that she needs this math to be reversed if she has any hope - which she doesn't - of claiming the nomination.)
His count stands at 1984 - 41 delegates away from the nomination. (Her count stands at 1781, and she needs 244 delegates to win the nomination. There are only 277 delegates who are not spoken for, and that only includes 191 superdelegates. You do the math.)
I won't be able to keep this updated until Sunday, but DemConWatch is an excellent source of delegate news. (Congrats to them for being selected to attend the actual DemCon in Denver.)
