Forget about illegals sucking up taxpayer funded welfare, and other socialist programs.
Forget about drugs and other criminal activity that thrives on the open border.
Forget about terrorists entering the country from our open borders.
Think, just for a moment, about TB. That's right TB. It is making a HUGE comback in the US. Why? People with out visas, and proper medical screening, just walking in to the country.
TB is an air born respiratory illness. Look here for the symptoms: http://en.wikipedia.org/wiki/Tuberculosis
Just today the CDC was able to stop a traveler from coming in to the US with "super" TB. A strain of TB that is very difficult to treat. (http://www.reuters.com/article/domesticNews/idUSN2934397420070529?feedType=RSS&rpc=22)
The only reason we were able to stop this guy is because he was nice enough to come in to the US legally. Had he done with millions of illegals have done, he would be walking around on the streets infecting others right now.
TB was nearly wiped out in the US, now it is making a big comeback as our hospitals, schools, and workplaces fill up with illegal, potentially disease caring, aliens.
If the terrorist, drugs, and just plain criminal workers don't get you fired up to solve the border issue, then perhaps a vision of your child coughing up blood will.
