I've been incredibly frustrated with a lot of analysis on this subject. Markovits makes complete sense to me, and he at least captures the most surprising part of this entire interaction.
I really wanted Clinton to win the primary. I knew a number of people who were passionate about Obama. I thought they were, ahem, delusional.
And I still do. They're mostly disappointed or even disgusted with him now. Meanwhile, I'm _incredibly_ happy he won the primary and then the general, altho I _still_ think those early supporters of him were wrong in who they thought he was and what he would be capable of. I'm a big believer in the process of negotiation while simultaneously intensely pessimistic about what is possible to accomplish through negotiation. If I were _optimistic_ about the possibilities of negotiation, I'd probably hold very different opinions.
