"Legal immigrants hate illegals.They will vote for Trump.”

Assuming you're talking about the Hispanic vote, most of them are already in the Democrat camp. And if they aren't, Trump's other policies towards Mexico, and the impact it will have on them, aren't going to endear him to them.

You are correct. Hispanics vote overwhelmingly Democrat because: Firstly, as a group (yes there are many exceptions) Hispanics do not assimilate fully into U.S. society and thus they need the government to tip the scales in their favor through affirmative action programs, subsidized medical care, etc. Secondly, they vote Democrat to give immigration benefits (open borders, amnesty) to their non-citizen brethren.

Republicans like McCain and Miami Rubio cave in completely on point number two, amnesty and borders, but as GOP-ers they really can't go too far on point one. So what they accomplish is alienating white voters while making little headway with hispanics.
