The Left's Tea Party?

Wilkinson's theory about Wisconsin's protests:

There’s something about the union demonstrations in Madison, and the excitement it has caused on the left, that reminds me of the Tea Party. I think I’ve figured it out what it is. The advent of the labor movement is at the heart of the left’s sacred creation myth. The sense on the left that unions are under siege gives the them something to fight for with a bracing sense of historically-rooted identity and moral authority. Similarly, the sense on the right that America’s foundational values are under siege gave the Tea Party something to fight for with a bracing sense of historically-rooted identity and moral authority.
