Would LBJ be happy about that? Something's broken with your theory. (By the way, to think that Hispanics move to the US simply to collect welfare demonstrates that you know zero about the situation. The overwhelming majority of illegal immigrants collect no welfare at all.)
And why dont a larger amount of illegals recieve welfare? Fear of deportment. Eliminate that fear and the roles will soar.
It's sure not extinct in counties with majority Mexican or Black electorate Dawg.
And the Mexican populace will only grow. You're ignoring all empirical data....especially nationwide. The Mexican vote for Dems in Texas will only grow from here on. Bush got higher than usual since he is native son but the only reliable "hispanic" conservative voters are Cubans (God bless em) and various South American professional expats. Soon enough Texas will look blue enough like the Valley and Bexar look now.
