I didn't think Rubio would get out tonight. Soon, yes. But not tonight. And yet there it is. It was a contradictory speech in many ways. On the one hand he was clearly standing against Donald Trump's politics of division; on the other arguing that the "political establishment" betrayed the Tea Party waves of 2010 and 2014 - which is in many ways the sort victimization politics and raising of false, hopeless expectations that laid the groundwork for Donald Trump.
Certainly one of his more human moments, certainly a difficult one for him. You can see the emotional anguish in his speech, affect and how he's carrying himself.
