Convinced as Sanders is that he’s realizing his lifelong dream of being the catalyst for remaking American politics—aides say he takes credit for a Harvard Kennedy School study in April showing young people getting more liberal, and he takes personal offense every time Clinton just dismisses the possibility of picking him as her running mate—his guiding principle under attack has basically boiled down to a feeling that multiple aides sum up as: “Screw me? No, screw you.”

But more than any of them, Sanders is himself filled with resentment, on edge, feeling like he gets no respect -- all while holding on in his head to the enticing but remote chance that Clinton may be indicted before the convention.
