No; I did not see a single thread on that. I know progressives are supposed to be for open borders, but I will say this. A LOT of DUers are out of work. They are in pain, just as is any other person who really, really needs a job. I’m not sure amnesty by fiat will be all that popular even at DU.
Otoh, if it is unpopular, they won’t dare to say so. DU is operating under new draconian rules that sternly forbid criticizing Obama. They are walking on eggshells right now, and none of them are liking it all that much.
