Links to polls? Every poll I've seen from the invaded border states are overwhelmingly for closing the Mexican border until this invasion is stopped. I see you don't live in a border state, but I do, I live in California, and illegal immigration to our state is costing California taxpayers 10 billion dollars every year. For us, that alone is more than enough reason to close the border, not to mention the mess in the schools, the hospitals, the social services, etc. etc.
We rarely see any more legal immigration from other countries. Los Angeles has become primarily a city occupied by Mexican illegal aliens and their relatives. We're being colonized.
