1) Joe Biden. Political polarization means you either adore Joe Biden or you find him unbearably grating, my colleague Gabriel Snyder just noted to me. I think this is generally true, but in my case, I actually find Biden both grating and adorable, at the same time. Maybe last night he was more grating than usual, but he certainly has filled my more partisan Democratic friends with a kind of provisional joy (unadulterated joy comes, if it comes, after the Hofstra debate next week).
2) Paul Ryan. Ryan held his own against the histrionic and condescending Biden, and I thought he was more fluent on foreign policy matter than I expected him to be, given that this is not his area. I thought the Iran discussion was muddled and disconcerting (because Biden was going soft -- at least that's what it seemed like to me -- while Ryan's "tough" position simply mimicked President Obama's tough position on Iranian nuclearization.
3) Bibi Netanyahu. All across the globe, 200 foreign leaders are asking their advisers, "How can we get mentioned in an American presidential debate the way Bibi gets mentioned?" It is remarkable, these two men fighting over who agrees with Bibi more, and who knows him better.
