Cyrano: I believe the concept of The Anchor Baby is largely a myth. This is based on the 14'th amendment, and has been repeatedly argued. It falls under the same type of mis-interpretation as the 2'nd amendment argument in my opinion. An illegal immigrant mother is subject to the jurisdiction of her native country, as is her child. This is just another issue that we are spending tax dollars on arguing in the courts, which should be a non-issue anyway IMO.
A quick search on "Anchor Baby Myth" or some such combination should yield pretty quick research material.
If you want to get a quick blood-pressure spike, take a quick look at how much it costs to put illegal aliens through public school. Then adding benefits for college on top of that is...well, it ought to be illegal.
