Democratic delegate calculator - CNN.com
Cool program that allows you to visualize the delegate proportions and see how the math makes it impossible for a Clinton victory.
Even if she gets 85% of the vote in both West Virginia and Kentucky, Somehow wins Oregon and Montana with 60% each, Wins 85% in South Dakota, and takes ALL of the vote in Puerto Rico, she would still need more than 60% of the remaining super delegates to swing her way in order to beat Obama by 4 delegates.
Clinton said on day one of the campaign that it's all about the delegates. Then what is she still doing in this race?
