Evidently, Obama’s pick of Doyle demonstrates that he isn’t into making nice with Clinton (warning: graphic language):

The donor, speaking on background, said that everyone in Clinton circles knows the two have hard feelings towards one another and haven’t spoken since Clinton removed Solis Doyle as campaign manager, and that Clinton loyalists view her with deep suspicion and believe that she is shopping around a book deal and acted as a background source for an extremely harsh Vanity Fair piece about Bill Clinton.

Not surprising, Obama strikes me as someone who would hold a grudge.
