What he's gonna do? Rename his guest-worker program with something the sheeple will understand, like entry-and-exit program?
The problem with his guest-worker, or "entry-and-exit", program is that it's all entry and no exit. Once the aliens are allowed to come in, they will not want to go back, nor will anyone be able to make them go back.
And what about the children of these illegal aliens who are born on US soil? I bet you they will become automatically US citizens.
Now there is a slam dunk for you. Bet all you want. Bet the farm!
The birthrate of the 15 million illegal aliens will be explosive. The number of Mexicans here will exceed the number of nonMexicans in short order due to the high birth rate. Third World here we come. China will rule the world. Why? Because they guard their borders.
