The reason why Obama will never be FDR is that his empathy is with the elite and their system. For all the rhetoric. And for all the words, he cannot lead a popular movement. Thus when he mobilized an army of small donors to propel him into power he was not being true to his biases. It was a pragmatic response to the fact that the elite had already chosen Hilary Clinton as their candidate. When he won, the elite shifted to rein him in. They should never have worried: his choices of advisor have conformed to the elitist view.
