You don't get around much do you? If you did, you'd find out the anger is increasing across the board on this issue. Americans that are truly informed on this march to national suicide are solidly against illegal immigration for many reasons that should be obvious to anyone with half a brain. I know that leaves out many folks who listen/watch to the MSM useful idiots or those working for "the race". If your #'s were even close (which they aren't) initiatives like PROP 200 in AZ would never have passed (which it did).
I get around quite a bit, and yes, I see that immigration has gonbe from 2% to 5% in the past three years or so.
The reason that the immigration issue is not being addressed to the degree that most in here would like to see it done, is because politicians know that there are other issues that Americans consider more important.
The moment that immigration hits double digits in a poll like this, you'll see action.
