There aren't "11 million" illegal aliens living in the shadows, there are closer to 50 million. Remember, not all the illegals were amnestied in 1986, about 5 million were left over. So, add those to the 2+ million, or so, net illegals that have arrived each year since 1988 when the amnesty period was over and you easily have 50 million illegals looking to take advantage of the proposed amnesty. Remember, for every illegal alien caught at the border between 3-5 (on average) make it through to the cities. Since no president since 1988 has caught and/or deported over 3 million illegals per year, we continue to accumulate illegal aliens -- like compounding interest, it tends to add up over a quarter of a century.
