The automatic citizenship seems to be a red herring – but the numbers are interesting, roughly 300,000 babies born to at least one undocumented immigrant each year. There are only 4 million babies (overall) born each year in the US – so it is a relevant discussion.[/quote]
I agree. It might be relevant. Except that the net migration from Mexico has been zero for the last 5 or 6 years. (Thanks Obama) So there may be a steady stream of babies born to at least 1 undocumented parent. But the number of new undocumented is remaining unchanged.
