The constitution DOES NOT SAY:
"Anyone born in the Unites Sates is a citizen"
It says:
"Anyone born in the Unites Sates, AND under the laws and jurisdictions of, is a citizen"
I may not have the exact words- but you can see there is a MAJOR difference between those 2 sentences.
I think that all these illegal aliens with so-called 'anchor babies' (a child born in the US to an ILLEGAL alien) are NOT citizens
The courts beg to differ.
The exception is children born to diplomats and invading armies.
