When have immigrants not voted left since mass immigration was first allowed in the 1850s?
Why is ending immigration not viable, why should Americans face a future of a billion people smothering each other?
Your Pew data encouraged me to dig further. I am encouraged that opposing any form of amnesty is a position that the Republicans can take and still win an increased share of the latino vote, since other issues are more important. Advocating an end to all immigration would be political suicide. Do you have data that would indicate otherwise?
