Exactly. I have come to believe that Hispanics voted 70/30 for Obama for the same reasons that Blacks voted 94/6 for Obama. They are voting for the party of redistribution. The low wages that illegals earn are supplemented by taxpayer funded benefits. A country with generous social services cannot be an open border nation and expect to survive.
I lived in a border state and watched the transition as we became majority Hispanic. Lower academic performance, higher crime rates, higher rates of illegitimate birth, higher taxes, an overburdened county hospital, and a rise in Mexico first mentality. I am all for immigration, so long as the policies implemented provide a net positive to the country. Neither party will do this.
