I walked with some of those folks on Saturday. I walked with nurses who have been trying to do their jobs in homes without water. I walked with retired autoworkers who wonder why the golf courses get to be hundreds of thousands of dollars in arrears while they lose their water for owing $150. I walked with old women and young men, and old men and young women, who were demanding the most basic democratic and the most common benefits of the political commonwealth, and almost all of them were amazed that they had to march for it. That was the overriding feeling in the march — a kind of exhausted incredulity that they were marching for water.
