That is one disturbing theory. What would we do if they all showed up at the border?
Building a fence won't do it. After all they'll be Refugee's fleeing a repressive regime, donchaknow.
Let's all meet at Mi Tierra's in San Antonio. We'll eat Tex-Mex (Highly edible and better than Mexican cuisine) and we can sing along and learn a few songs from the mariachi's so we will be ready for Joe's "anschluss" of the New Norte Americano Federacion.
Is this a plan?, or what!
