Obama adviser Samantha Power resigned last week after giving an interview in which she called Hillary Clinton a “monster.” It was the right thing to do, I think (the resigning, not the name-calling), but her exit from the national stage is still our loss: she brought a very nuanced view of foreign policy to the campaign, and she’s done a great deal to elevate the issue of genocide with her remarkable book A Problem from Hell: America in the Age of Genocide. She says she doesn’t really believe Clinton is a monster, and given the time she’s spent writing about the world’s true monsters, you have to take her at her word on that.
