A few points:
This started in 1965 when Ted Kennedy got the law changed on who can immigrate into the US.
What says or gives some natural right that people can just come to the US?
The Founding Fathers were as smart on this issue as they were on many others in that they felt the only ones who should immigate to this country were those from Europe because of like people build societies based upon a similiar culture.
There has been, and will contiue to be, nothing but net negative effects on this country by the current immigration problem.
Hispanics continue to vote democrats because they are for they like the Santa Claus mentality of the democrats and second, they come from counties with centralized governments.
