Pseudo-Licensed Eye Doctors Without Border Fences

I guess that Rand Paul tag was a pretty good idea. Check out his immigration plan - an underground electric fence. I notion so fantastical that even Republican Senators have the same reaction that the rest of us do:

National Republican Senate Committee Chair John Cornyn (R-Tex.) assumed it was a joke.

"I have not heard that," the Texas Republican said. "Underground? What would happen? How would that work?"

Fucking underground electric fences! How do they work?
