The longer it goes without BHO securing the needed superdelegates, the more her position improves. And what about MI and FL? Actually, she has a strong argument - that she does better in the key swing States that the Dems need. I don’t think she’ll concede until BHO actually has the needed number.
Hillary has a very strong arguement. However who wants to anger the black voters by throwing Obama to the back of the bus.
The democrats cannot win without strong black support in many key states!
