Mitt's - son of an immigrant becomes a "nativist panderer".
Romney, although proudly proclaiming that his father was born in Mexico, is in fact a bold-faced panderer and cheerleader for nativist anti-Mexican sentiment.
In 1912 George Romney, together with his family, fled the upheaval of the Mexican revolution and traveled across the American border to work in Idaho agriculture. (In this regard "Paisano Mitt" ironically shares a common heritage with millions of Mexican families who traveled to El Norte to seek a better life.)
However, wedge politics, being what they are, often require shedding inconvenient baggage that does not comport with the extreme right wing narrative. On the one hand, "Paisano Mitt" conveniently trots out his Mexican origins when pandering to Latino Republican audiences. But on the other hand, "Paisano Mitt" never fails to reaffirm his right wing so-called anti-amnesty credentials when wooing Tea Party Republican voters.
Clearly, "Paisano Romney" believes that such nativist pandering will help secure him the Republican nomination. (Early in the debating season, Romney endorsed the border fence with Mexico, and has opposed any path to citizenship for the millions of undocumented Mexicans living and working in the United States.)

Of course, Romney's grandfather undoubtedly had all of his documents in order when he "fled the upheaval of the Mexican revolution and traveled across the American border to work in Idaho agriculture."
