Walls. Let me just say this about walls:
I am against them. Everything I love about this country is intimately related to the idea that we don't have walls. We don't try to keep people out. Instead, we are that unique country that welcomes people from all over the world to come to our shores, to try to make a life here. Just check out the best places: New York, Chicago, L.A., San Francisco, Austin. They are all thriving, seething, over-stuffed melting pots. That's the great American experiment. And it's beautiful, wonderful, something to celebrate.
