He hasn't responded to the danger of porous borders because it hasn't been politically costly to him.He hasn't responded because he doesn't CARE what other people think.
When he tried the shamnesty he found out what the average American thought about it.
He already KNOWS that the average American wants our southern border secured.
He doesn't CARE what others think or want.
HE knows best what is right for America and that's all that matters to him.
He hasn't responded because by May 2009 the universal identification chips will be mandatory in all driver's licenses in the U.S. By 2011, all of the UK will be chipped and by 2017 the rest of the world will be chipped with Universal I.D. It was supposed to go forward this May, but there were delays. Don't you guys read. He's not hurrying to build the fence or reinforce the borders because in about 12 months, you won't be able to buy toilet paper without that I.D. As each of your licenses are renewed, you, too, will have the universal I.D.
No matter where you go, you will need that I.D. to do anything to keep body and soul together. When that becomes as useless as the social security numbers because of fraud, the only way to secure your identity from fraud will be implanted chips in humans.
