To me, President Obama's speech [http://www.nytimes.com/interactive/2012/11/06/us/politics/06-obama-election-night-speech.html] was a message about the importance of shared -- national -- identity. It was about living together through the good times and increasingly tough times. You could forgive him the moments of triumphalism as efforts to encourage and praise the citizens. I am a little less worried this morning, even though our process of "self"-government is harder and harder because of all the problems we face. Change can be good, but with all of these problems and all the uncertainty, good change needs to be sustainable. Sustainability means we work through the problems together, and it's going to take more than four more years. That's why we need to stick together and show each other our shared commitment. I can't imagine another way.
