I thought Hillary prevailed for the most part, but Bernie was fiery, and had his moments. When Clinton bragged that she’s supported by former Nixonian Secretary of State (and war criminal) Henry Kissinger, I thought his rebuttal was outstanding. He justifiably ripped Kissinger to shreds, and Hillary seemed genuinely shocked at Bernie's ferocity. It was the first time I've seen her somewhat speechless at any time during a debate.
