Hillary Rodham Clinton is taking on President Barack Obama with the same issue he used against her in the 2008 Democratic primary: foreign policy vision.

Obama lacks a specific doctrine, according to an Atlantic magazine interview with Clinton, the unannounced presidential candidate who is leading Democrats and Republicans in 2016 polling.

¡°Great nations need organizing principles, and ¡®don¡¯t do stupid stuff¡¯ is not an organizing principle,¡± Clinton told the Atlantic¡¯s Jeffrey Goldberg, also a Bloomberg View columnist, in reference to the way Obama and his aides describe his approach to foreign policy.
