Our current LEGAL immigration policies are turning the entire country blue. It is just a matter of time. You can't bring in 1.1 million legal immigrants a year, 87% of whom are minorities as defined by the USG, and not expect electoral consequences. Since 1990 over 25 million legal immigrants have entered the country. Two thirds of them will vote Dem once they attain citizenship.
In 1970 one in 21 was foreign born; today it is one in 8, the highest in 90 years; and within a decade, it will be one in seven, the highest in our history. In 1970 there were 9.7 million foreign-born and today there are 45 million.
