BEN, Ben, the short and the long of "it" is "we" don't "need" you. Don't make it something it ain't. Mexico is emptying entire towns and still whore house Vicente prances around making those ... uh ... statements. He's a public nuiscance ...both sides.
Entire Mexican towns are void due to the venture north.
Do states along the southern border (AZ, NM, TX) support inititiaves? (I already know CA does) What are the chances of something in, say, TX authorizing a state-based border patrol a'la Arnold's suggestion? Maybe his idea deserves to grow :)
I'm sure you have seen the demographic projections. In 15 years there will be no more mexicans available to come to the US. If you think having too many mexicans is a problem, wait until there are not enough.
