Wall off the border? LOL.
That will be the Maginot Line of immigration.
They'll swim around it.
If they really want to end illegal immigration, they should end NAFTA.
Closing the border will slow illegal immigration to a trickle.
And enforcing the laws against the employment of illegals will do the rest.
Unfortunately, the President thinks these scofflaw employers should be 'helped', not punished.
And his patchwork of enforcement along the border is a joke.
