But there is something seriously problematic about radicals and progressives in American politics. Some say it's the two-party system that squashes third parties. Some say that it's the potentiality or expanse of the middle class that marginalizes people that want to reform the system itself. Some make a sort of psychological analysis, that the left doesn't want to win, that success means co-optation. All of those things have some merit.
