Bush has known about this problem for years and he has done nothing. A major mistake because you can bet there is going to be violence, even if Congress and Bush kiss up to these people.
Bush, pass presidents and Congress had a responsibility to keep our country safe from invasion and they did nothing. Now we have allowed all this trash to come in to the country and we have to either deal with it or become a cesspool like Mexico.
Ideologues are ignorant of history. In 1836, when the Texas Revolution occured, there were already more Anglos north of the Rio Bravo than Mexicans. The Power of the Comanche had prevented the settlement of Mexicans north of San Antonio and it was only a small city. Austin had been invited to establish a colony because the Mexican government wanted a buffer between Indian raiders and the Mexican settlements.
