No, they will have to deal with you!
Let me explain:
1] the number is low--probably 15 million.
2] about 5 million are here that came here illegally in the 1980s-early 90s and have become citizens but never assimilated and fly the Mexican flag. That takes it to 20 million.
3] Once manest hits, all the chicos and chicas, tias and tios, primas and primos, and dozens of other relatives and even amigas and amigos will find there way here in a hurry--add on about 50 million more. That takes it to 70 million.
4] the birth rate. The birth rate of theirs dwarfs the birth rate of American citizens. Look to add another 50 million babies real quick. That takes it to 120 million.
5] As quickly as you must say, "Debo apprender Espanol", we will be in the minority, the slum USA will be ruled by Mexicans, and we will be the ones carrying banners begging for representation that they control. The Senate, the House and the White House will be run by Mexicans.
