The political center isn’t constituted by a handful of Democratic Party politicians, nor is it frozen in time or in its views. Instead, It is a broad and fluid belt in the Democratic Party as well as a significant force in many mass organizations, including labor. And in recent years, its politics have shifted in a liberal/progressive direction in the face of persistent social problems, failed policies, new popular movements, and existential challenges.
Any notion that the center isn’t a major and necessary player in the effort to decisively defeat Trump and his Republican acolytes next year and move the country onto a progressive trajectory in the years ahead is wrongheaded and worse.
