Flailing GOP candidate NJ Governor Chris Christie is trying to out-Trump Trump, and so has proposed tracking immigrants like FedEx packages. Christie even fantasized that if elected (yeah, right) he would bring in the head of FedEx Frederick Smith to help him with this problem. Presumably the unobtrusive Big Federal Government of Republican Chris Christie would insert microchips into immigrants so that they don't overstay their visas. Or there's another option, a guy named Adolph something tried it in the 1930s and 40s in Germany to keep track of certain people... "Those who do not learn history are doomed to repeat it." And be big fat jerks.
