It's not about bipartisan politics. It's about La Raza!!
What was odd to me was that the Republicans mentioned are, I think, Cuban. This legislation affects mainly Mexicans so I am not sure why they would fall in line with their Democrat collegues.
By the way, even though some will tell you "La Raza" is a fringe group and in many ways it is, never never discount the power of these groups. After all, fringe goups such as NOW have rewritten vast amounts of our legal code which affects nearly every business and individual in the US.
