The success of Donald Trump's anti-immigrant campaign surprised many. But I show that it was actually a continuation of a long-standing Republican strategy that has targeted immigrants and minorities for over five decades. It is not only a long-term strategy but also a widely successful one. Analysis of the vote over time shows clearly that White Americans with anti-immigrant views have been shifting steadily toward the Republican Party for decades. The end result is a nation divided by race and outcomes that often favor Whites over immigrants and minorities.
