Several posters here,of whom I am one,keep trying to tell people that the typical Spanish-Speaking illegal alien is MUCH more likely to vote conservative than leftist. Not only because so many of them are practicing Catholics,but because they come from leftist countries and fled their home countries to get away from leftism.
Yeah,they are likely to vote left when they first get here IF THEY EVEN BOTHER TO VOTE because they have no money to speak of,no jobs,and no place to live,and the left provides them with all of it.
Give them a couple of years to improve their English language ability,and they are off welfare and public housing,on their own,buying houses and paying taxes.
They are also,for the most part,very friendly people. I lived in a "Mexican neighborhood" in Denver,and never had any real problems with any of my neighbors. They even helped me without me having to ask.
