DC is frigid. Buses unload outside the Martin Luther King Jr. Memorial Library. A row of men in hoods stand in front; one figure is curled on the floor, moaning. A dirty man with pigtails hanging beneath a Nike cap struts and mutters. Behind him, on the library wall, is a quote from MLK: “Human progress is neither automatic nor inevitable.” The city is not crowded with people, but things. Obama is on buildings and Winnebago’s, and flatbed trucks lined with porta potties are everywhere.
