The anchor baby provision of the 14the amedment is based on a U.S. Supreme Court ruling that says, "in the absence of any legislation passed by Congress," those born on U.S. soil are U.S. citizens. In other words, Congress could have ended this travesty long ago, but has declined to. The amendment was written to include former slaves in our body politic, not pregnant third world parasites who manage to stagger across the border and have their babies so they can get on the taxpayer funded gravy train. For a good explanation of this, see:http://federalistblog.us/2005/12/birthright_citizenship_fable.html

Sen. Jacob Howard, who wrote the Fourteenth's Citizenship Clause believed the same thing ... as evidenced by his introduction of the clause to the US Senate as follows:

[T]his amendment which I have offered is simply declaratory of what I regard as the law of the land already, that every person born within the limits of the United States, and subject to their jurisdiction, is by virtue of natural law and national law a citizen of the United States. This will not, of course, include persons born in the United States who are foreigners, aliens, who belong to the families of ambassadors or foreign ministers accredited to the Government of the United States, but will include every other class of persons.

Clearly, something else is at play here, or we wouldn't be having this discussion.
Perhaps a lower appeal court ruling that was never challenged?

It would be useful to know both the original Supreme Court ruling cited, AND the subsequent ruling which rendered the first ineffectual...

The link below an excellent site, with lots of names and dates as starting points for serious research.
Unfortunately, most of the contents is opinion, rather useless unless consistent with Supreme Court decisions concurring. Those links are not provided.
