A reader draws my attention to a line buried in Chertoff's response to the "no match" injunction:

Today's ruling is yet another reminder of why we need Congress to enact comprehensive immigration reform.

I wonder what Kaus would think of that...if Chertoff is trying to "heighten the contradictions," he can't be too disappointed with this injunction: it shows just how "unworkable" the current tools for enforcement are!
