First, you can’t lump Robert Reich in with Ralph Nader. About the only similarity between the two is that they’re both further left than Bill Clinton and the DLC. Nader’s not even a Democrat.
Second, why–as a Democrat–do you consider the progressivism of, say, Robert Reich, Paul Wellstone, and Russ Feingold to be “bad rubbish”? Like it or not, it’s at least as valid a political ideology as the Democratic Party’s newfound market centrism. Do you have evidence to show a wholesale popular rejection of progressive tenets like social investment, economic populism, campaign finance reform, or a comprehensive safety net? Again, as a Democrat, do you feel that things like the collective bargaining, the minimum wage, Social Security, the FDA, and OSHA are “bad rubbish” as well? These were all enacted by the Robert Reich wing of both parties. The Republicans largely jettisoned their progressive wing decades ago, and personally I don’t see the value inherent in a political spectrum in which the Democrats are increasingly doing the same.
In short, could you elaborate?
