Bernie Sanders will probably lose the Democratic nomination to Hillary Clinton, after his impressive but inadequate showing on Tuesday. But the Left still won that night.

The Sanders campaign has energized and galvanized a big chunk of people, especially young people. And it has made it routine to talk about “socialism” in polite company. So as someone who has been out in the wilderness talking about Marxism and socialism for twenty years, I can’t but love it for those reasons.

But inevitably, there’s a layer of inexperienced activists who have such an affective investment in the campaign that they lose sight of the bigger picture. They make out this one politician to be more significant than he is, while at the same time misunderstanding his real value.
