The Sanders campaign has certainly sharpened the contradictions, hasn’t it? It’s been very clarifying to see Hillary Clinton and her surrogates running against single-payer and free college, with intellectual cover coming from Paul Krugman and Vox. Expectations, having been systematically beaten down for 35 years, must be beaten down further, whether it’s Hillary saying that to go to college one needs some “skin in the game,” or Rep. John Lewis reminding us that nothing is free in America. A challenge from the left has forced centrist Democrats to reveal themselves as proud capitalist tools.
