In an Atlantic interview with Jeffrey Goldberg, she turns on her former boss.

Clinton had many kind words for the “incredibly intelligent” and “thoughtful” Obama, and she expressed sympathy and understanding for the devilishly complicated challenges he faces. But she also suggested that she finds his approach to foreign policy overly cautious, and she made the case that America needs a leader who believes that the country, despite its various missteps, is an indispensable force for good. At one point, I mentioned the slogan President Obama recently coined to describe his foreign-policy doctrine: “Don’t do stupid shit” (an expression often rendered as “Don’t do stupid stuff” in less-than-private encounters).

This is what Clinton said about Obama’s slogan: “Great nations need organizing principles, and ‘Don’t do stupid stuff’ is not an organizing principle.”

For the sake of advancing her own political career—because you don’t eviscerate the commander-in-chief this way if you’re not running for president—Clinton has just made the last two years of Obama’s presidency significantly more difficult.

From a purely political point of view, I can see the argument for doing so. But I think this betrayal tells you a lot about Hilary. Nothing—not even loyalty—is going to stand in her way. Perhaps she feels she has reached the level where people owe loyalty to her and not vice-versa. Or perhaps she just doesn’t care.
