Cong. Sensenbrenner made an egregious error by pushing this Statist-enabler through the House. That was a doozy of a mistake. He chose not to fix the real problem--INS and State's sloppy/stupid/careless visa and immigration policies. Rather, he chose to impose a "Your Papers, Please!!" regime on actual citizens.
He should have known better, but the Wisconsin Legislature can fix that. And they should.
