The de-laboring of American liberalism.

I've been reading a bit about the popular front in recent weeks, so this caught my eye (h/t LGM's twitter). The relevant quote:

Finally, it's somewhat disheartening that these events have received virtually no coverage in the progressive blogosphere, outside of labor blogs. Nothing from leading individual bloggers like Yglesias and Klein, nothing from TPM, nothing on Kos, nothing on Huffington Post, nothing at Think Progress. If I've missed something, let me know, but these key events in liberal politics are receiving absolutely zero coverage from people that should care deeply.

When did labor stop being important? I can haz popular front nao?
