Oh, the left is going to be downright distraught.
I took a gander at some of their forums after the incident (DU in particular), they were very excited about the possibility that this could be some sort of right wing domestic terrorism.
This whole Pakistani American connection very clearly stinks of Islamic radicalism. The left will be deeply saddened by this turn of events.
I was over there, too. They were dying for it to be a Tea Party operation.
