Go to the health deparment of any large city in the Southwest or California, and take a look at the people lining up for free health care. It's true, you can't tell an illegal immigrant just by looking, but on the other hand, you'd have to be an Oprah not to be able to recognize the probabilities in those crowds.
"Go to the health dept of any large city in the SW or California and look at the people lining up for free health care...."Oh don't worry about that,GW says the federal gov is going to cover the bill(s) for illegals that don't pay/sarcasm intended.
