How many Mexicans will come across the border illegally today?

I don't think anyone knows for sure, not even our much vaunted Department of Homeland Security. (And that is a joke in it's self.)

But all the estimates I've read are around 1000+ per month.

That'd be only 12,000 per year -- which is a bit low. Did you mean, perhaps, "per day?"
